Hey CrystalD and all,
Wow, this is very interesting to me honestly.
I'll do a text version since that's what I feel like doing at the moment 
So, let me start with the questions.
1. What is your disability and how does it impact you?
I am blind, like, totally blind since birth.
as for how does it impact me, of course it does, to be honest I think that every disability impact's the person in someway or an other, no matter how much the person tries to combat that, but then again, the more you try to beat your disability, the more you will succeed in life.
Being blind impact's me in so many ways.
I will try to list a few.
a. Gaming:
I am a gamer, I like to play games, and so being blind, unfortunately I can't play those games I've been dreaming about playing, games like halo, metal gear, cod, gta, and all sorts of games basically.
I know I know, I can do it by just listening to audio and hearing my footsteps and stuff, but still, for me it is not enough.
Some games aren't even playable by blind people at all, like pokemon go for example.
If we're talking mobile, the game either have to be accessible with voice over so I can play it, and if it is not, then I am totally out of luck.
One an other thing regarding gaming, I like to play chess, I know there are some accessible chess games for the blind, but what if I wanted to play against stronger chess engines like stockfish, that's not possible because the gui for the programs that has this engine are not accessible with nvda, so I can't play this way, if I can see, I will not face such problems at all.
b. Accessible software:
Each app I want, if it is a sound editing app, a music app, an app for doing just a surten thing I want to do like managing files etc, or really any app I need to use, it need to be accessible with my screen reader or else I wouldn't be able to use it.
The list goes on and on and on, not just to computer related stuff, even to my personal life, but I will talk about that when answering the next question.
2. What is the most common misconception that you experience in regards to your disability?
I wish I can say just one misconception but unfortunatly there are many.
A. Using smart phones:
People think a blind people can not use smart phones, like iPhone, samsung etc.
If I use my phone infront of a sighted person, they will start throwing all kinds of questions at me.
like, How can you use this phone and you can't see the screen? etc etc etc
b. When going out:
Last September I was in a trip, I wanted to go out to the Dubai mall and pay the appstore a visit, I needed a replacement for my iPhone 6s battery.
I was alone, I booked an uber ride to the mall and went there.
When we arrived, the driver asked me:
How can you go alone?
I told him it's okay and why not.
He started telling me about how big the mall is, and how even the sighted people can get lost in it etc etc etc.
In all honestly, he was right, even sighted people can't move inside the mall with out a map, but say that to an adventurous type person and see if that effects him or not.
I told him it's okay, I can manage, I called one of the secuirty guards and he hhelped me, I did what I had to do in the mall that day and then came back to where I was staying.
I don't use a cane because it is not common around here, and society need a lot of improvement regarding that, at least that's how it is around here.
4. Do you do anything to combat these misconceptions?
Honestly, if I had the time to do it, then why not.
Once, I wanted to go to do some shopping, I booked an uber ride, and when we were on our way to the store, he started asking me some questions.
Like how did you book the ride? how do you use the phone?
I started explaining to the guy that we have something called voice over and it can read what's on the screen for us, it can read apps like whatsap, twitter, facebook and even uber.
I can open the app just like a sighted person can, and book a ride just like everyone else does.
I showed him how can I move around the home screen and stuff, and he was really surprised, he was thinking that we can not use smart phones before I explain to him that we can.
So yeah, if I had time to explain to a person that we can do a surten thing, like going out, using smart phones, using computers etc, of course I will be happy to do it.
But tell me how can you combat those who are staring at you while you're using your phone at starbucks, hell, even when I am not doing anything people still stare at me like me being there is a miracle from god.
5. What more do you think can be done to combat the misconception around your disability?
I honestly don't know how to answer this one, but I believe that blind people should start showing that they can do anything they want.
I don't have a solid idea as for how to go with it, but I think no matter what, society will not change, so we have to deal with it.
Honestly, I wish people know more about white canes, and what it means when a blind person is holding one, when that happens, I can happily use one, but for now, it is more trouble than helping.
On the other hand, like I said earlier, on some points, I kind of not blame them for how they think, I mean, if you look at it from a sighted person point of view, and this blind person comes to you asking you can you drive me to the world's biggest mall?
The first question you will get in your mind is how can he move around, sighted people get lost in it, even sometimes they lose where they parked their cars at etc etc.
I know this needs to change, but it's a very, very hard change.
I have a lot to talk about regarding this topic, specially because I like to travel when I can, and this enables me to meet all kinds of people and see how they interact with me and stuff, but that's all for now.
Thanks for this grate topic CrystalD, I believe this is my longest post in the forum
