Rant, help, anything?

Tilley
In the past 3 months my dad has had a heart attack, triple bypass surgery, carotid artery surgery, 2 seizures, and a ministroke. Ive been with him the whole time through all of this, and have been the one driving him back and forth to doctors and hospitals. He finally got out of the biggest and arguably best hospital in the state on Friday. On Saturday my SO called me to tell me he was going to the ER. His diabetes is getting worse and he has MRSA which has gotten into the bones in his foot and he might have to have his big toe amputated tomorrow. My dad still doesn't know about my SO because I live with my dad and my boyfriend is 37. I'm the baby and the only girl, and for 18 years it has been me and dad constantly. I need to tell my dad, but I need some help reassuring me that I'm okay or... anything? I've been in the hospital with my SO every day since Saturday once I'm done running my dad to appointments. I hate feeling like I'm neglecting one to be with the other. My SO totally understands, but without my dad knowing he doesn't get it. I feel like I haven't actually taken a breath since December... and today my SO'S parents asked me what I thought they should suggest to my SO but I... dont know... his whole family loves me and says they trust me to take care of him. I really want to move out and move in with my boyfriend so that I can take care of him but I'm really uncomfortable leaving my dad with my stepmom who didn't see him in the hospital 4 out of 8 days he was there last time, and didn't go to the hospital with me when he had his heart attack. I'm so torn!
