If you have other suicidal thoughts stop them right away and do sth anything that can get your mind off those kind of thoughts , like walking, playing , eating, singing, cooking , sleeping ( probably you won't get much sleep) but anyway look for sth that can get you distracted right away if you couldn't do that talk to a friend, and if you don't have friends start making friends (I can be your friend if you want, I need one too), and I know a lot of these things are hard to do when you have those bad thoughts since my sister have depression and was on meds for a while but try ,the important thing is to try and not give up , hold onto your dear life
