Stressssss

So I'm in college and pregnant with my first baby. The father and I are no longer together and he's been talking all sorts of crap about wanting half to full custody. Both my parents have been in and out of the hospital for heart surgeries in the past month and my dad's may only fix his problem for a few months before he needs another surgery. My brother and SIL are living with us right now with their 3 week old daughter until they can close on a house and move out, and they're set up in the room across from mine which means I'm sleeping on an air mattress in the basement so I can sleep through the night while I'm taking these classes. I've had continuing morning sickness pretty much daily and I'm 26 weeks at this point. I feel like I'm drowning in stress and I don't know how to make it stop 😳
