Am I depressed? Cant sleep. cant sleep.

I feel lazy all the time. It's not just lazy but demotivated feeling everytime. I thought this feeling was temporary but it didn't pass. I'm more like an ambivert or i used to be.but now I feels lyk an introvert.sometimes I shut myself completely frm family & friends lyk not answering  calls nor texts or not being in touch.The things I used to do which made me happy doesn't make me happy anymore. I don't find satisfaction. Getting out of the bed in the morning is now difficult.like why should I get up if that upcoming things of the day doesn't gonna make any difference or happy.sometimes I do wanna talk to people or try make things easier & better.but I can't.evryday I try to but it's like forcing myself to pass each day. I used to be happy around my friends but that too feels irritated. I pretend everything's fine. The minute I turn away frm a conversation with anybody my body  drop. I was pretending to be okay lyk putting on a mask infront of the people.confused and empty.cant sleep.
