My mind is spinning out trying to figure out how to protect myself (31f) whilst dating someone who is having someone (30f) major anxiety issues. 

We started dating about 4 months ago, first few months were great. All going in the right direction. There’s a fair bit of distance between us because of where we both live but I’m in her area regularly and she even came to visit me. 

Three weeks ago she took on a big business project and is also still working full time at another job. she’s under a lot of stress to get it all sorted and it’s made her anxiety go through the roof. At first I just noticed she was not responding to texts much, not showing any interest in me - all the sweet messages about missing me etc had stopped. I was mega triggered but kept my head on and eventually did ask what was up. She said about being stressed etc. then I went down for my visit and she didn’t want to be anywhere near me, very few hugs, none of the usual cuddles or holding hands or any intimacy at all, she was barely talking to me. I suffered through the trip feeling sad and on the last night said we need to talk and she was great, gave her full attention and she explained she just feels completely shut down and she’s used to going through this on her own etc I said a lot of the right things I think and said let’s just take it easy till she gets through this tough period. Now I’m back home and she’s not really talking to me etc and I’m trying to learn about sever anxiety and just keep my head on about it. 

But I’m hurting and I feel like my feelings don’t matter in this relationship anymore. The anxiety is completely taking over everything and I don’t know how to support her, how to support myself or when/ if things will go back to how they were. Do I just have to wait this out and talk about it all once this anxiety of hers calms down? Should I be talking about my feelings now? I’m worried that will stress her more. Will this get better? At what point do I have to just look out for myself and walk away? I want to make it through this.
