Feeling Isolated and Misunderstood During Covid-19

I feel like I'm at my limit with being able to make the people around me understand why I'm still taking covid so seriously. They acknowledge that it's hard and lament I can't do stuff, but that only makes me feel worse and bitter and feel like they just don't care enough to examine why their behavior is partially responsible. Even my mom who I've been podding with for 2 years now and has overall been really supportive and conscious of why I am where I am in all this, will just say things almost in passing about feeling disconnected from people and how it's not that bad anymore except for the "unlucky". And I don't know if it's just that I've become more sensitive to that kind of stuff through this, but it just makes me feel bad that the rest of the world is so ready to move on and wanting to, so much so that being supportive still has an amount of "why haven't you accepted it" to it. Trying to point out why it feels ableist and makes me feel bad is only met why pushback that it isn't, to the point I no longer know if I am actually overreacting. I'm tired of watching even the people I care about who say they care about my safety and health be so cavalier about it, just ignoring the fact that they're making themselves more and more at risk each time. I'm tired of the way people react to news of my continued caution and isolation as though it's something I need to work through to become more comfortable with the new normal. I'm tired and anxious and sad and lonely and just need to feel a little less like I'm the only one still out here. I think I just need to feel a little more seen and understood.
