Any success with medication?

I'm hella depressed at the moment because of limerence, I've been prescribed mirtazapine, just wondering if anyone has any experience with this or any other medications?

Is there anything that can actually stop limerence - it's especially difficult because I want to seek closure, but I'm not even able to send a single text to my LO without risking being put through genuine torture with the obsessive thoughts and nightmares etc... - is there essentially any pill that can chemically prevent you from sinking into a deep depression or weaken your romantic attachments to people? I can cope with normal feelings of rejection that puts you out of it for a couple days, but not limerent rejection that goes on for months.
