I’m having trouble cumming 😕

So my boyfriend broke up with me for no reason about 2 weeks ago. Last night, I was horny so I tried to masturbate and usually, I can get myself to cum in about 5 minutes or so, but I couldn’t last night. I just tried again a minute ago and I couldn’t get myself to cum again. I tried a vibrator, a dildo, and my fingers. I even watched porn, which usually works when I can’t cum. Nothing works. I don’t know if it’s because I’m upset from the dumping situation or what. Does anyone have any tips?
