TLDR; Do you need to have a severe (are there even different ‘levels’?) mental illness before a GP writes you a plan?

Hi. My GP is writing a Treatment Plan for me. My dire necessity to dissect every detail of life has me here and I need direction. I need to know I’m not alone.

I was diagnosed with post-natal depression 5 years ago. Started antidepressants and have been fine up until now.

I am SUFFERING more than I ever thought possible. I went through a difficult time just recently. It was definitely due to my own actions (drugs, affair etc.) but I’m trying not to blame myself. Which is hard because I have done things that I DESPISE myself for. I guess I’m trying to reassure myself that how I FEEL isn’t due to my actions. Is that reasonable??

Two weeks ago was the first time I’ve ever been 100% completely honest with my GP about what I’m feeling. This is when he decided to take this route. What does it mean? I know deep down that what I am suffering with mentally, is not depression (based on my very basic knowledge of the brain). I think I’m pretty equipped to deal with whatever happens however I’m so scared that I’ll manipulate myself into holding back. This could avoid the perception that I’m ‘using’ mental illness to alleviate the pain caused by what I have done.

Or am I just overthinking it?
