I'm having suicidal thoughts what should I do?

I've had them for a long time but I usually ignore them and they go away, but recently they have gotten a lot stronger. I just don't think there is any point to all of it, I feel like I don't belong in any thing no matter how hard I try. Then I look at this world and think of what I have to look forward too senseless violence, economic trouble, and just a life time of being hurt by people and treated like crap by people. Is there any thing I can do to get rid of them?
