Why everybody else but me

Everytime I go outside and see normal happy people it shakes me up inside. I press my lips together, and shut my eyes in tension. All the people that I used to know, just normal guys got it all. Money, house, car, relationship/marriage. Everything. All these people were just normal, nothing special, most were dumber than me academically, similar or worse socially. Many were younger. Yet all of them got it all together, got awesome jobs, get paid well. Got everything. Why is it that everytime I try to do something I fail? I do great with things, any complex problem I can solve as long as it doesn’t involve dealing with people. When it does, I always get rejected, told off, shat on, tricked, and used. Nobody gives me a decent job. Only the shittiest ones where I break my back and end up not getting paid a dime anyway. Girls always reject me, no matter what. I’m not an ugly guy either, I have little money, can drive my dad’s car, have a house to myself, my dick is fine too. But no matter what I do I always end up getting fucked over. I’m 26 virgin and lost hope long ago. I’ve been like this for 4 years and it does not get any better at all.
