Im so worthless and unwanted that whenever i think anyone has any interest in me they stop texting or delete me cause they got what they wanted from m

Guys will screw me but never actually wanna be serious about me. I dont understand because I have a lot to offer but I'm not wanted like that. As soon as they use me they dump me. No more texting or they delete me off snapchat. It breaks my heart and makes me feel worthless
