My advice:

Get away from social media and pick up some hobbies away from the internet.

I only have Reddit because it’s anonymous. It really fucked me up having Facebook, Instagram, tik tok etc. I would see how happy everyone was and I would think ‘why am I not like that?’ Id post to be like these happy people but I wasn’t.

I started deleting my social media apps one by one, no one cared that I stopped posting either.I’ve been much happier since!

I hope this helps you.
