I've saw in Tedtalks, they said you need to feel connected with people to feel less lonely. Try to schedule a meet up routine with your friends, or maybe join a new community maybe through the same hobby. Try to connect with people and have a meaningful conversations with them.

But hey, maybe you're tired right now and maybe you focus too much on your tasks. You've done well, you did amazing, now it's time for you to unwind and reward yourself ok?
