I have no sex drive help

So not long ago I used to have a huge sex drive I used to want it everyday and my boyfriend used to love me for it and used to worship me but for the last few months I’ve had no interest in it at all I’ve not even been horny or thought of sex and when I do I struggle to get wet or horny. Me and my boyfriend broke up because I didnt just lose interest in sex I lost interest in everything I hardly went out or did anything I completely forgot I even had a boyfriend so I never spoke to him or bothered with him I didn’t speak to any of my friends and I’m still the same I’ve tried with other guys but just can’t get in to it. What could be wrong
