My OCD and fear of hurting people?!

Im 21 yrs old and healthy but i have OCD. At first i just had it for little stuff like checking doors and water and the stove and stuff, however about 6 months ago i had a close call when i was driving my car and ALMOST hit someone while driving. That kinda scared me b/c when i got home i thought " hmm did i hit that person" and that feeling stuck with me for weeks. I was afraid that i did hit someone and that i was gonna go to jail. I kept watching the news everyday to make sure noone in my area got hit by a car. Eventually that terrible feeling disappeared and everything was good. Now i have a fear of hurting people when Im in public. I mean I would never do this cause i just wouldn't, but i feel this way. I never had a situation where i was in a fight or close to hitting someone, i just kinda started thinking about it. Its basically when I am alone with someone like in a public bathroom, i fear that i would hit them or hurt them. Again i would never do this, but it is just a feeling that i have...how can i get rid of this feeling? I am going to get help but in the meantime how can i try to overcome this. I know its only OCD but it really scares me that I would go to jail cause i convince myself that i did something when I know i didnt. So what can I do.
