As someone with social/general anxiety, I feel the same. It's like, everything I normally worry about has been banned for the past few months, and I've got used to being comfortable and happy. I actually had covid which wasn't fun (I had anxiety about catching it before, but obviously once I'd had it that calmed down), but other than that I've just spent time with my boyfriend, video chatting with family every so often, and still working as I worked from home anyway!
The thought of getting back to normal scares me. I had agoraphobia a few years ago and had to slowly build myself up to getting out and about, and I feel like this has enabled that behaviour again, and set me back a huge amount. So I understand the necessity to get back to normal, but I do worry about it a lot.
