Afraid of being seen as a pervert/pedophile (great anxiety)

[cielonero]

I never had the courage to talk about this in real life, because of what other people would think. Anyway, I will explain my situation.
I'm a 18 years old male, and for a year now I suffered of great anxiety, related to this thoughts that always pop in my head. Everytime I see/hear a child, I have the terrible fear that someone will think I am a pedophile. Because of this I start acting weird, and my fear increases even more, while I think that people will notice my anxious behaviour. All this made me ask myself if I'm really a pedo, but I don't feel any kind of attraction towards children. The same problem I had, but with other subjects: for example, if I walk in a road and there's a woman ahead of me, I feel like she thinks I'm following her and I want to rape her. This has become an obsession, and I'm totally crippled by it. I left school, and I don't go out anymore. The only time I'm out of my house is when I'm buying weed, and I feel like everyone I see is laughing at me, or thinking I'm weird.
I searched on the web, and I think this may be OCD, but I don't have any compulsive behaviour, or at least I think.
I feel like I'm leaving out a lot of things. Like I'm afraid that my female friends (or even males) think I'm attracted to them. I hope I can find some good advice here, because I really don't know what do, my life is basically just weed and videogames now.
Hoping to get an answer, I'll leave this post here now. Ask me whatever you need to.

It may be the weed, friend.  Many people become paranoid while smoking it, and methinks you've become one of them.  First step, stop smoking pot.  It may not be agreeing with you.  Second, this isn't OCD, but it is obsessive thinking, and it's time for you to see a psychologist and figure this out before it becomes so chronic and much harder to get rid of.  In the meantime, anything happen in your life that might be triggering this?
