So, in summation, you think the strikes against you are your disabilities, low income, unemployment/inability to keep a job, living with your parents, looks/physique. You think your selling points are not being religious, ally to lgbt, liking techno, having an IT degree and being a part time student.
Are you asking for advice? If so what kind? Style? Job hunt? Relationships?
You've seemed pretty resistant to other suggestions so I hesitate to say anything. Hesitation over.
Style - T-shirts are casual. Fine for a college campus (undergrad, not graduate school), working out, weekends. But you say you have 6 of these exact shirts, in different colors, and felt they were worth $32/each? WHY! And some people could take offense to this t-shirt... if you are hoping to portray yourself as an offensive nudnik than this is what I would suggest you wear.
How would you like to be viewed by strangers? If you want to be taken seriously, this is not the T-shirt for you.
Job hunt - From this post I don't think sales would be a wise option for you. Temple Grandin wrote an article on jobs suited for people with Asperger's. Identify your strengths and look for a job that fits you instead.
Digging yourself into more loan debt without a goal is a terrible idea.
Relationships- Work on your self esteem first. You have to feel good about being you, no one wants to be around someone who doesn't even like themselves.
Easy way to improve your self worth: walk for 30 minutes outside everyday. Gets you healthier, releases serotonin in the brain (helps depression), gets you out into the world! That's where you could meet someone.
If you find an exercise activity you enjoy, you can also meet someone with similar interests that way.
Start a hobby that isn't solo.
Volunteer. Association for the Blind might be a cause that's important to you. Or some animal shelters have volunteers. A million opportunities.
Those are ways you can feel better about yourself and possibly meet other people.
