I have to fight a strong sense of doom and hopelessnes every day.

I copied this thread from another fellow sufferer:

Negative Thoughts About Yourself

"Is it a withdrawal symptom to have negative thoughts about yourself?"

Yes, very negative thoughts that my very existence is stupid and worthless. "Why am I even here? Life is ridiculous!" --- those kinds of thoughts creep up and tear at your soul and make you detached from reality and ungrounded, scared and alone to your core.
