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, that's what we do to cope, right? Tried journaling and other things too for years but nothing helps and people around me dgaf and i don't have anyone too. ( I want to say a lot but I just don't know how to explain it :⁠,⁠-⁠))
