I'm there myself with my gf and I've been to that road for two years now.
I always thought that I'm protecting her from something and since she has her own problems I do everything to help her. I've sidelined my problems for so long, which hasn't been easy and now it has started to show again.

(So what I can say is not to be like me, really!)

But I've promised myself if I can get through this and if I can get the help I need, I'm going to reward myself by being open and sharing her things that I haven't been able to share before.
Right now I'm too fragile and too scared of other things to do that. I have to go one day at a time..
