You say you have no support system and therapy is out of the question.
This forum can provide you with some support, but the support is much warmer on the psychotherapy forum!

Do you have any hobbies that you could do socially?

Why is therapy out of the question? I see from other posts that you have a dentist, so you must live in a reasonably civilised country!

I haven't found any references to you having a job or a church.
