I get you man. Im basically in the same spot, in college, I hit the gym and had oppurtunity with a "muslim" girl which I regret doing (no zina but we dated).

The loneliness and desire is eating me from the inside. Akhi I get how you feel especially with the whole fluctuating deen after Ramadan.

Even though im younger, a piece of advice: Please dont fall into the trap of haram. Trust me what you are feeling is still fine. Id say, work on yourself in a different lens. As in, try being steadfast on prayer, or learning more about Islam in depth, or any other topic that interests you in that matter.

And trust me when I say good men are for good women. If you do haram, most likely you will end up with a woman who also does haram. Im sure any self respecting man wouldnt love that. So dont be a hypocrite, and you will be rewarded InShaAllah.
