Question

I have a very strong sexual drive that causes me, almost everywhere there are girls, to feel a strong and uncontrollable urge to “hit on them” or “flirt.” Modest dress does not help very much to reduce this urge for me. In the past too, I was much less careful about keeping distance in interactions with girls, which probably contributed to this.
The thing is that ever since I understood that I am not at all interested in these interactions and that they only cause harm, and I try to avoid them—that is, this is a completely irrational urge—it simply causes me very great suffering. Every bus ride, social gathering in a public place, or even just running errands turns into one long nightmare. I try very hard to guard my eyes, and sometimes I succeed, but not everywhere can that help. In addition, let us say at gatherings with friends in a public place, there is barely any enjoyment in the gathering because I can hardly divert my attention from the powerful urge and the struggle.
In this sense, the yeshiva is like heaven for me, a place where I do not have to suffer so much from this urge, and every time I leave it—for example, during the current break between terms—it becomes an ongoing nightmare.
The point is that I understand I cannot live like this forever, shutting myself up within the four cubits of the yeshiva and fleeing as much as I can from every encounter in a public place. On the other hand, I do not know how it is possible to act differently.
The question is: what is the right way to deal with this? Should I continue the distancing, try to avoid things as much as possible, maybe live in a Haredi neighborhood in the future, avoid every interaction with girls, and even avoid sitting in public places? Or is there something else to do?
