Anyone partly blame there family members for OCD?

And does anyone have any advice on how to stop doing that? Much appreciation for anyone who takes the time to read all of this one and give me some feedback because I really feel it is an issue that I need to deal with. So I partly blame some members of my family for my poor mental health which then led to OCD and even if I am right which im sure I am I want to stop feeling this resentment and the really negative feelings that I have towards them because I am 36 now and I know that it's no good for me and really contributes to keeping the OCD alive. I will be as a brief as I can be about what I am talking about although it is difficult. So I had what I would call an okay upbringing but I did sometimes witness my mother and father physically fighting and arguing when I was growing up. They both enjoyed a drink but my father become a full on drunk who never worked. Alcohol and drunkenness was a regular occourance particularly at wkends right throughout my family. My parents separated when I was 14 and I stopped talking to my father when I was 18. I started seeing him again when I was 23 which was actually nice as my condition was that he wouldnt be drunk in my company again and he stuck to it although out of the blue he commited suicide about a year later When I turned 16 I started to drink and become a typical binge drinker getting hammered every wkend although when I got to about 18 I started to space my sessions out and would regularly go a month or 2 without a single drink although when I then decided to have a drink I would always get black out drunk. I have continued this behaviour until the pressent day but I still tend to get really drunk every time I do. I have to say that when I got to about 29 I started getting more drunk than ever and although I would never physically hurt anyone I would become verbally unpleasant when I was drunk. Even though this would only be once every 2 months my mum started to suggest that I have some councelling so I eventually gave in and went to councelling but I actually believe that going to councelling wasn't a good thing for me because the councellor got me to open up boxes that I had either already dealt with or kept closed for very good reasons and I'm sure all of this contributed massively to the OCD. My councellor at that time also reckoned that I had a drink problem even though I was only drinking once every 2-3 months and suggested that I tried aa. This made me feel quite angry tbh because although I felt that I needed to stop getting so drunk when I did drink I didn't feel like an alcoholic and I actually enjoy drinking every couple of months. This whole thing has made me feel resentful towards my mother which is horrible because I love her and im sure she just wants what's best for me but she still drinks most wkends and still occasionally gets absolutley hammered. Apologies for the life story here it's just that I really need to sort out these negative feelings out towards her and towads a few other people if im to stand any chance of getting on top of my mental health
