Hello, Fourwalls, and welcome.

Because we're not doctors, we can't diagnose, but I can tell you that, in my opinion,
you have several symptoms that are characteristic of bipolar illness:

1. The spending sprees
2. The high-flying drive to sell, to become rich, etc.
3. The guilt and remorse after realizing you're spending far more than you bring in.
4. The loss of concentration, foggy feeling.
5. Failure to care for yourself properly, i.e., eating one meal a day.
6. Concern about death excessively and depression.

I think you would find seeing a psychiatrist very beneficial. Be honest with your
doctor, because that's really the most significant way he/she has of knowing what
your system is reacting to.

Take care of yourself first.
