bottling up your feelings may sound appealing, but that will only worsen it. write down your feelings and thoughts in a notebook, type it out in a notes app, talk about it to someone you trust, or talk to yourself about it. you don't have to bury your feelings deep inside.
and, remember that it is okay to ask for help. if you want someone to talk to, need some words of reassurance, a hug, or anything you might need, it is okay to ask for it. you and your feelings will always matter.
