I'm just saying this but everyone feels this. I have this sort thing happen all the time. I personally just fight it and sometimes I win other times I get depressed and take sanctuary in my closet. I think its just fear of rejection which if you think about it is 100% normal for a shy person to feel. Also in my head I'm not safe and warm I actually fear a bunch of stuff is gonna happen. I'm paranoid that way.
I've retreated to the darkness plenty of times, but you just don't feel full in that darkness which is why if you can't see the light you search for it or you make your own.
Before you ask I fear rejection a lot which is why most of the time I won't be myself around crowds of people. Its over powering but we just have to ignore oher people and be confident in yourself. Which is way easier said then done. Another thing I never do is show people i don't know at school my art because I fear they would reject me for it.
Just take as much time from the computer you need just know when you get back your friends will be wait for you to return. Feel better soon.
