how do i escape this...?

well as u all know, i broke with my first gf so far...and now i am back to loving that girl i used to love at school after i broke up with my so called "online gf", and this time i won't try to escape the fact that i love her by lying to myself telling myself that i love completely different girl who i never even met in real life...infact i won't even try to escape that fact but what i am trying to is escape this feeling of deadly depression because of the fact that she doesn't love me nor does she know that i love her and i can't tell her for some complicated reasons unless some stuff happen, i can't commit suicide, i can't do drugs and can't drink to escape this nightmare.

so guys this is serious, how do i escape from this self destructive depression?

please don't joke about it, this means alot to me.
because for that girl i am ready to sacrifice anything except my heart which beats for her and her alone.
her smile is such a hope giving one.

also, is hoping for her to love me one day a good thing or is it a foolish hope that is going nowhere?


Thanks in advance guys and merry christmas to ye all (also in advance).
