Is it start of a kinda depression?

I have nothing to do, no one to hang out with, my friends and bf went on holidays.

So I stay on my room, watching movies and YouTube.

I realised it's not good to stay at home doing nothing so I decided to do some shopping today.

But now I'm dressed, ready to go, I just don't want to.

Feel lazy and my motivation's gone.

I just want to stay in my bed, watching movies and being lazy.

I procrastinate, we're Friday and I had to do things before the week end and I haven't done them.

How do you explain that?

A friend of mine used to do this and it was because of her depression.

Is it the same for me?
