Jack honey - Yes, you need to stay on your meds, and yes, you have work to do - but really, a kid who squirts ketchup in your face??? And a mom who doesn't take control of the situation when the kid does?
Yes, it's normal for kids to resent a new guy in their mom's life, and to act out. But this sounds extreme. And it makes me question whether her parenting skills are up to the challenge, regardless of whether yours are or not.
I know it hurts to let go, but really, this sounds like a now-win situation. You can do better.
AS for your mood disorder - are you taking your fish oil? (Pretty good data on fish oil and bipolar). Can you go to a community mental health clinic to get help? Have you ever been checked for thyroid problems or iron overload (hemochromatosis)?
Meanwhile - although I know you don't feel like it, I want you to get outside and exercise today, okay? It's the best therapy. Just do it.
