Very sad and idk what to do. advice please

I got rejected from the colleges I applied to. I tried to follow my dreams but failed miserably. I can’t find a job, have no money or friends. Im afraid to tell my parents because I know they will be very upset. Everyone was expecting this and it honestly hurts more to tell others. Especially telling the people who didn’t believe I could do it. Idk what to do I feel so useless. I’m 20 and I already have peers married with good jobs or in school. What do I do?
