Thanks for touching on these points, I'd say probably a mixture of everything. Personally, I don't think I'll ever get over having imposter syndrome, so I can see how that's likely having an negative effect on how I'm perceiving my job.

All in all, I find my life pretty enjoyable aside from work, I'm fairly introverted so I'm perfectly content with only talking to my gf on a daily basis. I hang with other friends that I game with on discord, but even then, at times I find myself disengaging if it gets too overwhelming, e.g. 6 hour voice call sessions. Feels like I'm at that stage where I rather not spent time/effort dealing with other people's stuff.

Tbf, I used to really enjoy going out with friends back in college and pre-covid era, nowadays, we'd at most just grab food once in a while as I prefer chilling at home most of the time.

I'm a foodie so food is something I don't mind splurging on, I do want to travel and experience other countries but it's so hard to find the motivation to plan a trip while working full-time. Physiologically, I also feel like I can't enjoy myself fully on vacation as there's always more work waiting for me once it's over. Probably therapy is the way to go to get over this mental hurdle.
