Is your counselor clear on the fact that there was never a relationship to mourn here?

I think you need to contact whoever prescribes your medication and be very clear that you have developed at least 2 unhealthy obsessions with people who you never had a relationship with.

It's possible you need a medication change and/or serious therapy on how to interact with young women without turning it into an obsession.

One of my original thoughts was to tell you to volunteer somewhere to cut down on your free time to think, but you are likely to come into contact with young women almost anywhere and unless you fix the problem this is going to go on and on.
