One day I woke up sick

For context, I'm almost 22. I got sick at 18. It's not like cancer or M.S., I'm not going to die. But there's no explanation for the reason why I got sick. Nobody knows, not me, not my doctor, not the specialists. Mum thinks it's because I left home too young. Dad thinks I have too much anxiety and I'm sick because of it. My fianceé thinks maybe I'm reacting to my birth control or to natural hormones. I think I woke up one day and I was sick. It went just like that. Waking up one day with my stomach turning inside out. Shoulders heaving for hours every morning, Curled up on the floor of the bathroom, protesting the muscle convulsions. I woke up this way every morning for over a year and no specialist could tell me why. All I know is I'm sick. My fianceé didn't sign up to be a caregiver, Yet somehow he's thrown into the part. Today, if I travel, I wake up sick. If I stay at a friend's house, I wake up sick. Often, when everything is normal, I still get sick. I wake up at either midnight, 02:00am, or 05:00am and there is no hope of sleep until at least noon. There is overwhelming nausea, dizziness, muscles contracting violently and burning. There are my teeth which seem to be wearing away from my stomach acid. There is the feeling that if this has to be my life now, i don't want to live it. It's been 3 years since I had a single day without pain. I pop ribs out of place as I vomit, so even after the nausea subsides I'm left sore and often bedridden. My fianceé tries to ask how he can help, And I'm sent into an emotional spiral. "You can't help. I can't help me, my doctors can't - i don't want to do this tomorrow morning. I don't wanna wake up tomorrow if it'll be another day of this. I wanna give up." Today, I want to give up. I want the burning muscles to stop. I want to be able to eat something other than applesauce mixed with water and not throw it up. This doesn't feel like a life anymore. I just wanna get better already. I pray to whatever God listens that I get better. I cannot do this forever.
