Hi,
I specialise in Health insurance. I don’t know why Ditto says you can’t get insurance for OCD. OCD is not something insurance companies would reject just because you got OCD. I am more than happy to help you out get an insurance if what you say is just an OCD, it should be no issue.
PS: I am an Insurance Agent specialising in Health.
Edit: Yes, you can get another insurance through porting.
