im depressed

so here is why i am depressed , first of all i have everything man can have ( fit , good family, money and influence ) , but i can not simply go to women and talk, even if i talk i say weird things , also i always want to have more than i have , for example when i was living in normal house , i wanted bigger one, now i have big one, now i want mansion, also on cars , when i bought mustang for my first car i was happy , but then started to want new car, now i bought new x6 and now i want i8 , so yeah this is why i am depressed probably , but also i have one issue , guys who don’t have anything what i have , how they are happy , how they get girls , im polite to women , but not simp way , and still girls dont want me , when girl wants me , i dont want her , so how heck am i still normal, and how heck i am not in psychiatric facility , so i need someone who will tell me how to get girlfriend and how to live normal life , like others do , pls
