Dude, I know exactly what you are going through, my sister-in-law is in the exact same boat, only she is a functional four year old.
You need to get with the program, get your shit together, and start running a repair business rather than an excuse generator. Currently, you are on a path that will get you evicted from your present living situation, which will put you in dire straits.
Learn about EBay and CL. Talk with your vocational coach, and get photos taken of ten radios ready to sell. Post them on CL, have the buyer meet you at the local police substation for the meet/demo/sell. This means you must talk with your coach, your mom, the police, and your roommate, and then get your shit together. Excuse generators do not help with your situation.
If you want help with/from us, you need to disclose some info, like where you live and when yo can do a meet/greet. There are some great folks here, but you need to come across a little different, like you are asking for help rather than yelling at us. Quite a few of us have gone through situations like this within our families, so we are a good resource if you want to do things the right way.
