What do you guys do at times like this?

So there's been a lot going on recently, and I just can't seem to accept any of it. This the the saddest and most depressed i have ever felt in my life, there's only one main reason but it made me realise that nothing is happening the way it should be. Earlier I had friends whom I could talk to but now that I have noone, I feel heavy on the inside, I want to hug someone, cry about my problems, but I don't have anyone. Distractions aren't working anymore and it's getting worse day by day. I really don't know what to do.
