always Horny

Hello 
Im single but I bought a vibrator because I'm horny all day,every day. I don't know why?😭😭
I'm 30 and I have to use tons of lubs because I'm a little dry,  but I'm always horny. 😭😭
I use the vibrator but I only git 2 orgasms 😭😭
I'm not ugly but I don't want one night stands, I want a real relationship. Am I old? Why am I so horny? 
And I take diazepam, antidepressants and still horny
