Hi, Interesting..Easy..and difficult question at the same time...See there had been numerous studies on the heritability of OCD (I ASSUME you must have gone through them ) ..Some concluding strong evidence while some pointing only suggestible evidence..still widescale genomic association  studies are going on for more evidence ......Also interplay of Environmental factors interacting with genes play a role.....Also OCD does have evidence based treatment....But yes you have full rights to decide about future life keeping in mind positive and negative points...I advise you to consult a psychiatrist nearby for helping you in detail....hope it helps.
