Leave. No, seriously. When in remission, live your life. Not through a computer or through a screen. You'll have this weird moment (or at least I did) of not wanting to write anything for coming across as too chipper. Or to talk about my family because my excitement about doing things in the future might just be really annoying. I know that others probably don't agree with me on this because good posts are awesome too. When feeling good, you should surround yourself with other people that are feeling good. If you feel like you want to help some people for a bit back on the forum, then come back and do so, but not at the expense of your happiness. If it starts to bring you down, take a very loooooong break.
Try hard not to second guess your feelings too much. It can be odd. I remember giggling for the first time after my diagnosis. It was weird and giddy. Or dancing. Seems really silly, but don't stop because the former you wouldn't do it!
You will always hold onto a little bit of caution. You know how fragile the psyche can be. In some ways, this insight will help you judge people, trust in people, and be able to care for people in the appropriate way. This is all good. It's just a little bit of goodness that came out of all that badness.
Be warned that if the symptoms return, you will be very angry. I was surprised at my anger. I threw things, I shouted angrily to fate. "My life is fine now! Why?!!" But the struggles seem to not last long. You've already paved the way before so traversing is easier.
I've just begun to understand why I came back. I had dealt with the physical abuse and even the sexual abuse. But the abandonment...I had not addressed. So I'm working through that and am already starting to go back up. I'm starting to feel better already. Just be aware that there are many layers to abuse. The emotional ones may not seem as obvious, but they cut the deepest so we tend to keep them for last...for when we are strong and ready.
Hugs!
