Not looking for sympathy..

Ok...I just need to vent for a minute. I'm not looking for sympathy or anything of the like...I just dont have anyone to talk to. I've been with my fiance for 6 years next month. I love him and would do anything and everything for him, but lately I just want to leave and not come back. He is a disabled veteran with PTSD and numerous other mental health issues. Recently it's gotten to the point I'm happy to go to work or see that hes asleep when i get home. EVERYTHING lately has been setting him off and I'm just so lost anymore. I try to just stay to myself, but he blows up over everything I do. If I'm on my phone he yells st me then he will get mad if I dont automatically do something like Google if he asks me something. He's turned into an emotional abuser and he doesn't know what hes doing because of the PTSD. I'm just so sick to my stomach every single day...walking on eggshells when he is around. I still do love him, but I just feel myself pulling further and further away. I know it's part of the illness, but I just don't know how much more I can handle. I've started to fall into my own depression and have no help at all. All I want to do is sleep and just read stupid sh*t on Facebook. In the last year I lost about 90 pounds and I'm starting to not care anymore because of all of this and it isnt a just because I wanted to lose weight it was because I had to lose weight for my own health. I'm just over it and I needed to tell someone.
