what if youre depressed and you cant tell anyone and you feel like everything you do is wrong and you dont belong here anymore?

Talk to a listener, they won't judge and it's completely anonymous, so they won't have any idea it's you.

I think that expressing yourself is a good way to start. :) I know you mentioned that you can't tell anyone, and so if you are not yet ready, you can express it in another. Some people write in their diaries, some people make poems or find a new hobby. Some want to create something, to sing or dance it out. Some prefer doing something mindless to manage it. Whatever works for you, you find a way to express your feelings. But hopefully, you tell someone one day. 7Cups is a good place to start. :)

Being depressed is a very hard thing to deal with on your own. When I was depressed, I too felt like I couldn't tell anyone. But I self-harmed as well and some friends did found out about that. I wanted to tell people to get support but I as too scared. I really should have told someone, because I would have probably gotten out of my depression a lot faster if I had. So reaching out is to a trusted person is always a good idea. If you feel like you don't have a person to talk to, websites like 7cups are there to listen to you so you don't have to bottle up your feelings! Hope this helped

First, I would try to build my confidence. I used positive quote apps to help me think differently about myself. Little reminders throughout the day are great. I've received notifications of positive messages when I was feeling stressed, irritated, sad, and many other not-so-good emotions and almost instantly I feel better. It has helped keep me positive. I've also felt like I couldn't express my feelings to anyone; so I used to express them to myself. Meaning, I would write my feelings down or say how I'm feeling out loud to myself somewhere private. Remember life is beautiful! We all have a story to create!
