Has anyone experienced this?

My husbands family believes that covid isn't real. They have large gatherings in public, outside, inside, birthday parties, anniversary celebrations, holidays, etc. We have a 3 year old and I'm 15 weeks pregnant. My husband worries about socialization for our 3 year old and how important it is but for me, I find it inconsiderate that we have to always feel consistently guilty for not attending these get togethers. I'm so upset that this continues. Has anyone experienced this and what would you do? We are on a waiting list for vaccines but its been 2.5 months since we registered and nothing so far. The cvs near us wont offer it and neither do our doctors. We are stuck at home feeling extreme guilt. I can't do this shit anymore.
