You can't guess here in absentia. Because with OCD it is about the same as with depression - there is only one term, and there may be several conditions behind it. Including physiologically conditioned, which psychotherapeutically will not break through anything, only pharmacology.
But in general - yes, you can. If you're lucky. Since you, most likely, are not a psychodiagnostician (s), and without an examination you cannot say anything for sure, you just have to rely on luck and try to work on your own.
It all depends on each specific case - some are lucky and they independently find a way to get rid of OCD, but the vast majority of people need help. Unfortunately, there is an opinion that psychological problems can be solved by pharmacology (this understanding is most often present among doctors), however, there is one unshakable rule in psychology - if a problem is acquired by the psyche, as a result of its inability to adapt to existing conditions, then the problem can only be eliminated methods of psychology and / or non-drug therapy. Medication is most often required only to reduce the severity of the manifestation of problems, but not to cure.
