Caught Covid from my stupid extended family - less than 2 weeks post-op

So I’ve been staying with my parents for my surgery recovery and while my mom has been fantastic and totally on board with making sure I don’t get exposed to any germs (because duh any kind of upper respiratory issues would be terrible when I’m recovering from major surgery in my chest area and my immune system is more vulnerable than is already is (I’m immunocompromised) my dad has been far more lax. He cares of course but it took me yelling and begging to get him to wear a mask when we went shopping pre op because he just didn’t see the point (he has a fully working immune system and doesn’t get sick often). Me and my mom had to really explain that it’s of course it won’t make us 100% safe but at least it helps.

Well… time passes and im like a few days post op, then his parents caught Covid and his brother’s family caught the flu and my mom and I once again had to beg my dad not to interact with the sick people and to NOT under any circumstances let them over to the house while they’re still sick. He followed that rule until a few days ago. One of his brother’s came over despite feeling “under the weather”, this brother told my dad, who proceeded to not tell the rest of us and still allowed the sick brother and his family to hangout in the house and even interact with me. My mom and I didn’t find out the brother was sick until a day later and we were pissed. I don’t for sure know if I caught it from the brother but that’s my best guess because I haven’t really left the house since my surgery. Unfortunately I can’t even confirm if it was from the bother because the asshole refuses to take a Covid test (his whole family is sick now too to boot) (the brother is real piece of work so I’m not surprised, just pissed)

Last time I caught Covid I had horrible symptoms and developed Long Covid, POTS, and PTSD from the whole experience so to say I’m extremely stressed would be an understatement. Rn my symptoms are like that of the flu and while I haven’t started coughing yet I know it’s on the way because I can feel how my chest aches and it’s like there’s concrete slowly weighing my lungs down. I could really use some comfort, advice, solidarity, anything to help get me through this.
