Good morning @GothMum
I'm so sorry that your son is affected by OCD. Honestly, I think it's one of the worst silent mental illnesses to have. So much is misunderstood regarding OCD and someone that doesn't have it can't possibly know what it's like. I have been to see various counsellors and a psych to seek treatment and everyone seems to have different ideas on how to tackle it. It's just nuts.
Why is your son not taking his meds every day? He does understand that he needs them, yes?
Lately I have noticed that other members in my family have some form of OCD, nothing that stops their lives but it's still there. I wish I was that lucky.
I think rituals aren't in themselves a bad thing if they don't interfere with what you normally would do on a day to day basis. For instance, if someone was to count things or repeat things in their mind that to me would be okay. It's not causing any major issues. If these things help from having a meltdown then I think it's way okay to just do what you need to to stay a bit sane.
I am trying to research a bit more on the physical side of things with the OCD. Interestingly I found out the other day that as well as having serotonin in the brain, your stomach also carries a big amount of serotonin. The stomach and digestive track in the human body is referred to as the second brain. Sounds strange huh? Anyway, it's a good reason to make sure you stick to a reasonably good diet so things keep ticking along they way they should. This is also a reason that when you take a high level SRI to increase the serotonin levels in the body, you can get an upset stomach and even IBS because the stomach and digestive tract can't handle that much increase in serotonin. All very interesting.
From what I understand about OCD, there are parts of the brain where the serotonin is lacking, even though you can be on SRI medication to increase the levels. I would like to find out if there is a way to get the serotonin into those areas again, whether that's with drugs or some other way. I'm still delving into this but I'll keep searching for answers till I have exhausted all possibilities.
One thing I am finding helpful in the rituals I have is to be still and completely focus on what it is that my OCD is causing me to do. I find that when I'm more mindful, I can move beyond the problem a bit faster than if I'm just letting my mind wander and letting the OCD carry me away which is what usually happens.
I very much hope your son can get the help he needs to try to overcome the OCD. We all need to hang in there and keep fighting.
