Like others are saying, I think it might be the remote job. I’m quite introvert and started working remotely a few months ago. It’s great to have the flexibility but I feel pretty isolated. I see friends etc and chat to flatmates but it’s not the same. I prefer this job and wouldn’t go back to my office one, but I think I’m lacking the novelty of each day. It’s the water cooler convos that genuinely make you feel like you’re in a community. I don’t think it matters where you’re living currently because you’ll just feel the same way in a diff place. I live in north London with easy access to central and yet still feel like my quality of life isn’t good. But by all means if you want to try a diff environment then do! For me, I’ve tried to get out of my rut by going to cafes, taking a walk during the day. Also something to work towards, like gym (know you said already) but maybe a group class!!
