The options here are really limited and badly organized. It's like going through high school again but without the close relationship to teachers and people who can help you, and instead of in a school with people your age you go to mixed age groups full of immigrants, thugs, criminals etc.
Is that just an excuse you made, to say to others I can't do this, because of such and such. My IRL friend who has learning diffculties drops out of courses, a few which could be quite useful for him, because of excuses he has made up.
Have you not investgated all possilble options?
