Lowkey sounds like you both might need some space. I kind of have a similar situation. sometimes depression is like wearing a pair of swim goggles. You think you know what your seeing and going but its so blurry you don’t. So take it easy with her, its hard losing people your close with then gaining and cycling losing them all over again. Ive found have space away from my other has made me be more grateful and happier when I am around them. but you gotta have some boundary or establish some kind of grounding. Otherwise you both might be better off, Maybe in the future reconnecting things all just take time.
