I'm not worth it, am I?

Legit, having the hardest time right now. I feel like no one cares, at all. Like I am stranded here all by myself and no one even sees me hurting. I smile, because I want everyone else to be happy, but my mind is full of tears. I feel like I can't even pray right now, because I feel like God won't listen or care about me. I am nothing, after all. I push away from the people I was once close to, because I know all they will end up doing is hurt me. They kind of already have. I get treated as if I don't exist half the time, by the people who swore they loved and cared for me. I am just so hurt by a lot of others actions that surround me. I knew it all along, that no one really cared about me. Is this my role here on earth? I'd this all I am meant for? I feel myself drifting, far away from everything I once loved. I have started to notice how everyone talk bad about those that aren't around, and I know they are saying stuff about me. My anxiety is getting worse and my panic attacks are happening more often. I have been having a hard time controlling myself, and I was just starting to succeed. I'm honestly scared, and I don't think I can continue much longer like this. I've lost my trust in everyone and I've lost faith in myself. Truth is: I don't think I had any faith in myself in the first place.
