unwanted reoccurring thoughts

I have reoccurring unwanted thoughts that I have no control over. I try to ignore them or try to think of something else, but its like my brain is doing this on purpose to **** me off. The thoughts are either things of the past that are not relevant and that are over, or they are thoughts of things that are not appropriate. I often have a guilty feeling, although I have not done anything wrong.  I know seeing someone about it is the best thing to do, but what disorders does this link to, and do you think, in fact, that there is a disorder that I am suffering from? Thank you for your time.

Reoccurring unwanted thoughts are usually called obsesive thoughts. Psychotherapy and medication together are very effective for this problem.
