Hey everyone, not sure if this is the right place but I could use some help.

My finance (F25) suffers from anxiety and depression, I've (M26) recently started to battle with anxiety as well. But I need help dealing with hers. She wants space and to be away from people quite often she used to be pretty clingy and this change is really messing with me. I want to be held by her when I'm having anxiety. I know she needs her space and I just want to help her. Our relationship is having some issues and our mental health is an issue. I just need some advice on what to say what to do for her, besides just give her some space. Thanks in advance
