Is it normal that i'm like this?

It's like, for me, when bad things happen to me or someone says something hurtful I just bury it and things start to build up until one day I just lose it and start crying over something small because I've just let all the hurt build up over time.

For instance, for the past two weeks I've been in horrible pain, have barely eaten or drank, vomited a few times, and just felt like over all shit and I figured I had another ovarian cyst that ruptured because its happened to me before. I've had to leave work twice because of the pain and my father (I'm 18 but I still live with my parents for the time being) basically made me feel like shit for not going to work and pretty much called me a liar and said I was faking sick to avoid going to work even though I've told my parents I don't mind my job. Then I had to go to the hospital yesterday because of the pain and it turned out it WAS a ruptured cyst just like I had thought. And it's just like, nothing I ever do is good enough for him. I got 100's and high 90's in school and yet all he could focus on was how I only got a 60 in chemistry (because I was horrible at it). He gets mad if I take the car out to go hang with my friends and he gets mad if I try to put gas in the car too. And then today, it all just came crashing down because I was washing the dishes (which he didn't help me with, even though my arm is hurting terribly from where the nurse tried to drive in an IV and missed the vein and instead left a huge purple/black bruise) and explaining to him that I was going to be moving in with my sister next month and I'm in the middle of talking to him when he starts talking to someone completely different and I realize that while I was talking he dialed the phone and started talking to someone else.

And I was just so humiliated and upset and right now it all hit me and I've just been bawling my eyes out. The doctor at the hospital gave me a prescription for Tylenol 3 (I'm supposed to take 8 a day but I only take 4) and I was wondering if that's been the cause of my emotions? Because its made me feel very doped up and stoned and maybe it's also affected my emotions. I'm sorry, this is such a long winded rant and I'm just really upset, I know none of you guys probably care but I just needed to get this off my chest. Like, I don't even do anything wrong, I try to avoid doing anything that would even annoy him but nothing I ever do is good enough for him. I just feel useless and depressed when he's home.
