You're dealing with both impediments and social issues here. This would be difficult for anyone. I highly suggest professional help, but if it's not available or you are unwilling, the next best thing would be to understand you're going to need to fail a lot with intentions of getting better, and it may never happen. I'm rooting for you.
Edit: To clarify, speech therapy and general therapy are what you will benefit from.
I don't like sniper drones.
