Didn't think I'd need this anymore

I'm on meds for my mental issues now so I figured I wouldn't need to vent on here ever again. Well, I guess I was wrong. This is the only place I CAN vent without ridicule because no one I know knows that it exists. Well...one person does but I don't expect her to care, I cut everyone from my past out of my life. For starters, been battling a migraine for two days now, my shoulder still hurts ridiculously bad even on enough pain killers to knock out most people and to top it off, I have arthritis in both my hips. I'm 28 years old and getting out of bed in the morning is almost too hard. I can't even vent to the people around me because they're used to me complaining about the pain so they just blow it off. BUT I'm supposed to care about their issues and if I don't, I'm the asshole. I do so much for everyone but I get attacked if I forget to something trivial. I get yelled at when animals that aren't even mine, dont get fed on time. The kitchens dirty, my fault. Laundry isn't done, my fault. House isn't clean, my fault. Lets forget the fact that I WORKED ALL FUCKING DAY and the people in my house SAT ON THEIR ASS all day and did nothing. But it's my fault that nothing ever gets done. I forgot thats how it worked. When I get home I'm in so much fucking pain I can barely think straight, yet I'm supposed to take care of everything. I'm always told "if you need help, ask for it" The few times I HAVE asked, I got bitched at for asking. So..wtf am I supposed to do? I almost can't use my left arm due to nerve damage and walking is difficult and getting more difficult. 

I dont even know why I'm typing this. Mostly just to vent. I don't expect anyone to actually care. No one in my life does, so why would strangers on the internet.
