Happy birthday man...
Sorry I'd love to write a convincing and uplifting message but sadly today I don't fee tool great.
Haven't really celebrated my birthday since I was 18...
31 now and I hang with people like once a year, my 30th was at home alone.
Lots of anxiety and depression...
Hope you feel better soon though, message if you want, I'll want to listen! I can assure you I'm not too busy socialising instead! ;)
Sounds boring and typical, bit go for a walk somewhere you haven't been... Give you some fresh stimulation, and you'll feel a little less trapped being stuck indoors.
Would write more, but... I'm not feeling perfect, so I gave my best reply I could now.
Stay well! :)
