Hello ........
Welcome to the forum. It certainly sounds like you've never been to a good therapist. It would help a great deal to have a professional person to talk to periodically. Too much negative self-direction, and all of us need some help to get out of that frame of mind!
I would guess by what you've said, even though never married .... you have a daughter. And you stated that "your charged $395. amonth" for your daughter! I'm a father of two daughters - and divorced - and paid child support in one form or another (including some college costs) for 18-years.
There are court systems to be able to see your daughter .... unless of course you think she's a burden on you - and chose not to pursue that. I hope that's not the case. There are far too many flunky dad's around. So - go to a court and demand your rights as a father.
I am sorry to hear about your being on disability. In all states I'm aware of, the general rule for child support payments for one child are 20 to 25% of the annual salary. Please double check that too much is not being taken out of your disability.
Dreams ........ we all have had them. Nearly all of us have to deal with getting over our dreams - cause it just doesn't usually happen. And we all have to move on! I never became a film score writer - but i sure wanted to be one when I was 24!
And ..... how is it that you're forced into being alone? Please .... find a good talk therapist. It's the best thing you can do for yourself - and maybe even your daughter.
Finding happiness in some of your early childhood things is a great place to start a conversation with a therapist - and like "why can't I find it now"!
Time to find purpose and point in your own life.
