Don't give up, ANewDay.
You are not worthless.
I know that feeling after many failed attempts, trust me, I've had many times of feeling like you do-many dark nights where I felt that I just could not ever get myself together.
I'm new to this too, so I can't give much advice, but please don't give up.
I understand that you gave it your all, but there was something missing from your plan.
Perhaps reaching out for more support might help ?
