Everything is fine until it's night.

Awe baby, I'm sorry you feel that way :(( it makes me sad knowing what you're going through. Just know you aren't alone and I'm always here for you. I'll be your friend and I understand how it feels to be burnt out. Try to get some sleep and don't push yourself too much. Know when your body needs a break. Reach out for help. I know you feel like a burden but I promise in the long run you will be fine and it will be worth it. Eat regularly and drink water. Slowly clean your room and set goals not impossible goals just small goals you know you can finish and if not that's fine. 😕💞

That sounds familiar alright. Especially felt that after losing a friend or after a break up. Just the sheer contrast between having your day's full with someone to suddenly them not being there. It's like a sucking void.
And yeah I get thd whole wanting to be alone but also not be lonely at the same time. It's like you just want to be with someone but not want to be stressed having to entertain them and make sure they like you and won't leave from boredom. Like it would be nice to simply have company without having to worry about it.
And as an introvert with social anxiety I Def get burnt out easy from social stress. So yeah reach out when you can. Cause just maybe you will find the right people that you can just be you around.
