Wants2Fly,
First of all I want to say congrats for being so brave that you want to move to a better place to make yourself better.

Fear of back sliding- I think that this is very common especially when you are starting new. I have faith that you will do just fine!!

Guilt- This shows a sign that you are really a kind person. When I feel really good somedays I feel really bad that others (especially people here on the forum) might not be feeling so good. Be proud that you are feeling better!! That is a wonderful achievement.

Getting better- You are not a drama queen!!!! You are battling and overcoming something that can be very difficult to even keep your head above. Again this is something you should be proud of. Just because you are getting better does not mean that you should feel afraid to come back here for help.

Relationships-This one I do not have advice for because it is something that I am currently struggling with. Just give it time. I am sure that when you find people that you want to have a meaningful relationship with (friendship or more) then you will. Don't rush!!

Above all else take care of yourself.

Jessica
