How to bottle up everything?

I know it's not healthy for us but when we don't have anyone who listens to us and cares for us, idhe kadha manam chesedhi? Journaling Inka chala things ne try chesanu but nothing helps and when I reach out to people, either i get left by seen or "oh" ani reply istaru when I vent to them and it hurts so much.

and it just makes me feel like a fool when I reach out to people, so how do you guys bottle up everything? and how do y'all cope with it when you don't have anyone to talk to?
