I’m like a human revolving door

I literally can’t get men to stop using me... it doesn’t matter how I carry myself. How long I make them wait for sex. None of it, it’s like men walk into my life and after a short period of time they are gone..... everyone keeps telling me, your time will come. You’ll know when the time is right..... yeah right. I’m basically a worthless sack of shit... I just don’t know what to do. I’m about to be 25 and all of my friends are settling down and getting married and having kids.... and I struggle to not drink on a weekly basis! My grandma is worried that I’ll never settle down :( ugh I’m just having a rough night.
