Loneless

I don`t understand ... I`m young , interesting , funny , with sense of humor , smart ( but not a nerd) , sports guy and nice but yet i feel like most of the times everyone just call me or text me when they  need something but do they call and says "Hey wanna go somewhere sometime" Nop. I just wanna underestand why??.. In my entire life have been a dawm good guy if someone falls im fucking there to help but yet anyone cares about me ? Nop. Is it my folt for being too nice to peopel that doesnt deserv it ??? Girls look at my and see what ?? A skinny , almost sord of good looking guy but i think im good looking , im not a dawm model but im not the fucking troll under the bridge.
In the world i most have 2 or 3 true friends and the rest are just some lame losers and fakers...
Im simply trying to have a girlfriend and some friends (true friends).
Any advices??
