No longer in love after Effexor- young and numb

a couple of weeks after taking effexor (which I abruptly stopped on account of its adverse effects on my diabetes and ability to feel my blood sugar dropping) and then lexapro, i woke up one day, no longer in love, after many years. I am still young, very confused, and its terrible. and I havent even cried yet, which doesnt make sense, I just keep sleeping, hoping ill wake up in love again or something. If there was a medical explanation it would make a lot more sense, at least, i dont know. I thought serotonin was supposed to be like love, and therefore should it not make us feel more love?
