What should I do about my current state? I don't think depression for me has been this bad before?

Yesterday was one of the worst days EVER. I kept getting depressed again and again and I just couldn't find anything to be happy about. This morning my mother brought me down yet again, after my father brought me down last night. My parents have been a big problem for a while now. They are not very nice, which is why I make sure not to hang around them too much. I particularly made that choice today after having another dispute with my mother. When she started ranting I just waited for it to pass, I've had enough experience with my family, especially with my parents, when not to talk too much. Talking to my mother is a complete waste of time.

I can't be bothered with my usual activities today. I'm sorry but I just don't care. Watching videos I got off the internet seems okay, but playing games does NOT sound like fun with the state I'm in. I'm so bored today that I had to post this. This all started because of a bad experience that happened a couple of days ago. The problem is still kind of there, so with that, and the fact that it has caused so much trouble that I don't even know where or how to backtrack to my original thoughts. And it has caused a lot of hurt. That's the other side of why I'm feeling so depressed right now. My mood fluctuates very rapidly. There are lots of moments where I don't care about ANYTHING. I have never been so tempted to commit suicide. The only reason I'm feeling any kind of motive right now is because I'm typing this in.
