First off, you don't strike me as an individual with diminished capacity. Your written communication is well written. You convey your ideas in an understanding manner.

You've suggested you have barriers. What are you actively doing to remove them? They won't just disappear on their own.

Find yourself an advocate if not a friend. Perhaps you can obtain one at your local mental health association. Perhaps you might find a peer support worker. You should also be able to talk to a vocational support counselor. Similarly, the association will have a jobs board of employers compassionate towards mental health. Most communities have such a facility. If not, find the closest one and give them a call.
