We can't diagnose on here but a few things come to mind.
Have you had a thorough work up from your primary doc.
This may rule out some medical issue.
If all is ok there ask to be referred to a psych doc.
They can dx & decide on any meds or therapy needed.
If no ins there should be county assistance available.
There is no need to keep suffering when help is out there.
I wish you the best.
