Depression?

Lately I have been feeling really down. I cry myself to sleep. I wake up feeling worse, most of the time I just stare at walls or the roof. I act all happy and smiley around everyone but when I’m by myself I let it all out I just feel numb but I feel everything at the same time.one day im fine I’m numb the next day I feel everything. I feel alone, I do push my mates away. A lot of people have said I am depressed but I just shrug it off.

I do think of Suicidal thoughts late at night but I know I’ll never do anything bad to myself.I barely smile or laugh I don’t remember the last time I was actually happy. I feel worthless most of the time and I am just not ok anymore. There’s days I can hold it in and act fine but then there’s days where most of the time I can’t pull it together. I’m so fk lost I have a lot of mental break downs everyday
