Depression & loneliness leads my life.

I'm a college student.I felt depressed for the first time when I'm only 10 years old.I actually don't know then the exact meaning or term of depression but I can feel something is wrong.Day by day when I'm getting older I can understand nothing is okay and that time my mental condition is so weak.I realised this is called depression.I was habituated with this and after 3.5 years depression was gone.I felt so happy that time.But then lockdown,COVID my boards result broke myself.My ex boyfriend couldn't have any time to talk to me.Here's noone who listens what's i wants to say.I'm not live with my parents since childhood so i can't share a little things with them.Mumma will get hurt that's why I can't share my problems with her.In this whole world not a single person is here for me.So i decided to stay alone with myself.But I can't do it anymore.I always feel that I need a person with whom I can share my problems, thoughts, thinking.But noone is here.So my question is what can I do now?
