Is OTHER wrong in the post ? POST :  

Well, possibly bit of a long post, so beware. TL;DR at the bottom.

I  suffer from tinnitus along with some other symptoms that have been  getting worse lately. It's been about two years for tinnitus, but other  symptoms have crept up in the past little while. One of those is what  doctors are telling me is depersonalization disorder so my brain can  handle the tinnitus, which is apparently common.

The  feeling is near unbearable sometimes and it puts me on edge most of the  time. Stress makes it worse, fighting makes it worse. All in all, I'm a  total wreck with this right now and no fun at all to be around.

My  girlfriend has been intensely supportive during this time. She's come  to the hospital with me, she's been a really great support. However,  because of the heightened stress levels, we are fighting a ton more.  Well, this morning I said something she didn't like and we just sort of  got into this massive row. When we fight, my symptoms get a crap ton  worse and I turn into a jerk.

So, I told  her that I need a bit of space. Just some time to get a handle on my  own mental health problems. I feel that if I don't do this, our  relationship is going to end up going to hell and it'll never get  better. I told I'm just going to sleep in the basement and do my own  thing for like two weeks. And in the end, the intended result is for me  to be better able to function. She's not happy about it, but she  accepted.

We bought a house together, we  adopted pets together, we have a life that we are fully planning on  building together. I still love her and she still loves me.

Currently,  she's crying upstairs. I'm just sort of.. letting it happen because I  don't think it's the best idea for me to go console her when we've just  agreed that this is what we're doing. She has abandonment issues and she  wants to know what scope of our distance is going to be. I've said that  I have to figure that out and I'll get back to her sometime today.

Am  I the asshole for saying that we need some time apart? Am I a jerk for  thinking of myself? Am I an asshole for not being more attentive to her  mental issues?

TL:DR  I want some time away from the girlfriend for my mental health because  we argue. Not sure if that makes me the asshole or not. This is a  terrible tl;dr.
