need a help

Hello everyone !!!
so i am new to this forum !! and I write to talk about my problem which is like this, I feel strange emotions (I do not know how to describe them precisely), this emotions come to me anytime and anywhere !!! and they are intense and serious !!! when these emotions arise I think of things:
sometimes I think about the fact that I don't have a girlfriend to make love with and that others have it !!
sometimes I think about the fact that I don't make plans with friends and that others do !!!
sometimes i think about the fact that i don't have cool relationships with my family members while others do in front of me !!!!
the emotion is stifling !! and i need help !!!
thank you
