Vent

I've been having a flare up recently (working on a POTS and EDS diagnosis currently) and I have been struggling so much. I'm also a single mom. My son is 8 months old and we bedshare because he REFUSES to sleep on his own, will wake up every 15min or so in his crib so bedshareing is the only way for me to sleep. The issue is that yo bedshare safely I sleep in the cuddle curl position. So on my side, and doing this cause my knee, hip, ribs and shoulder joints to slip and be in a compromised position. I can barely sleep due to the pain. So my brain fog and fatigue have been extra bad as well. I have no idea what to do. My son also currently has respiratory infection and is having trouble sleeping due to that. I'm at the end of my rope and have no idea how to continue. My mom kept him for a bit the other day so I could nap and rest. I feel like a bad mom because I can barely do things with/for him. This just feels like an impossible situation and I don't know how to fix it.
