Bored with my life

Its almost 29 years m living my depressed life . I started working at 12 years of age since than i have been working but i cannt myself at any top level .still working as fincial analyst .I never had a healthy relation in my family society and never had expressed or can say that never had chanced to comunicate with others . But now i feel that its high time i feel that my mind is not working now even some body explains something i cannt understand its skips from my mind .Even m not getting bride who can marry me .i always gets emotional with others and people use me i always suffer loss even some people took away my job . I have lost all trust on people i try to do everything my self but now i am tired .
