Homocidal thoughts, I'm scared

Hello everyone

Recently there has been a rash of intrusive homicidal thoughts going through my mind and I believe I'm doing a very good job fighting these thoughts along with some irrational intrusive thoughts but there have been at least one or two times when it went too far. Now of course the chance of death is nil and I haven't done anything illegal but the burden of these thoughts and the actions are seriously ruining me. Like today I was playing with my rc car and I wanted to crash it on a bike that was my friend's since i did it before but just for fun and I thought it looked cool, anyways as I proceeded to do this I started to think about the thoughts and i crashed my rc car. Almost immediately after that I got upset at myself and started to cry. Well that bike turned out not to be my friends instead it was an old bike that nobody owned plus it wasn't even damaged but the guilt is horrible. Whats worst is that I don't think this was much of an intrusive thought since I didn't react to it as quickly as I would. It was unwanted until a second or two later. Help me please, what should I do?

Nobody can help me?
