Getting so tired…

So I got sectioned/committed into a mental hospital and they wouldn’t let me go for 5 whole months. I patiently rode it out and gladly got back home. I thought things would get better at this point but I’m having fights with my girlfriend over stupid little things and i’m continually thinking about death every second. I was looking forward to the new wow expansion coming out to focus on that and numb the pain but my girlfriend has an issue with it saying im selfish and dont want to spend time with her. I want to be dead and i’m envious of all the people who are now at peace. It feels like I’ll never find peace
