It is hard to figure out what the problem may be, without knowing you, so I won't try (feel free to PM if you want to do something like a mock interview).

One thing that may suck, but want to make you aware is that chances are you need to do things worse temporarily, before they become better. You may need to put extra effort now (go to community college etc), for reward later.

One program I'd suggest you explore is AWS Re/Start, https://aws.amazon.com/training/restart/ ... it may be right for you (Amazon also has a similar internal program).
