OCD is usually a compulsion to do something based on 'bad events will happen if they are not done' in a certain way. Also its important to remember not to get confused with 'quirky behaviour' because there is a line there like the fine line between 'low mood' and depression that often gets overlooked.
The intrusive thoughts and slight 'paranoia' (hate that word so much) towards others is not OCD, not in relation to someone going to physically harm you for no reason anyway.
My advice is do not watch soaps on TV or the news at anytime until things calm down for you as i believe both are poison anyway. Full of negativity that make people question things they dont need to think about.
As for the voices (irrational thoughts), if they get less and less frequent i wouldnt worry too much but if they remain at the same level or intensify then see your GP and ask about Bi-Polar as it fits into 3 or 4 different categories, not just mood swings as is the common trait.
Last thought is that medications have some really bad effects on people so you may want to change what your on to something else or slowly get off some altogether. If your not on meds thats fine, but if you are and your aking for advice, then i just gave you 5 years worth in my reply.
