You don't need to go into detail if you don't want to, but if your best friend doesn't know you've experienced this, it might help them to understand why you are having the mood swings.

I have started seeing a therapist. My best friend would actually get on to me for not eating. My eating habits have changed. Sometimes I will be able to eat and sometimes I can’t even stomach food. I’m trying the therapy in hopes that it will help in some ways.

I was told I’m not bipolar, trust me I thought about that. I have never acted or felt like this before the domestic violence situation...

Not bi polar but have major depression and ADHD

I'm sorry you are a victim of domestic violence. I can not imagine. One thing I've learned is it is difficult to impossible to control any situation. You can decide how you are going to act and say but the other person no. You mentioned that you suffer from PTSD....are you having treatment for that? I understand that lots of people get therapy and drugs for that condition. That would be my advice....what you can control is yourself. Start getting treatment for the PTSD. Thinking of you & wishing you the best of luck.
