Try to keep yourself busy, you wrote on your profile you play video games, whenever you have these kind of thoughts, try to clear them away buy getting involved into a game, or watch a movie that wouldn't have anything related to your problems in it. Usually disney movies tend to work, even tho theres alot of romantic stuff, they're quiet childish, and they keep your mind away. If you feel like they're loosing interest, ask them to hang out, arrange stuff, and see them more too, the more you hang out with them, and you have fun with them, it'll help move away from the thoughts.
