sad and depressed

Donno whats wrong and whats rght ..wehther soemthign is worth worry or not!..whether i am exaturating things or not..whether i there still is hope or i shoudl just give up!

every passing day increases teh distances between us..every word i say! or dont say..causes for a fight..am tired..sad..dissapointed..depressed..hopeless..never thoguth i would reach to this limit but i did i think! ..always iw as told: u r so strong! ur heart is like 7adeed! u dont feel! ..etc etc ..some i take as compliment and some soudn more like a 'naqd' but then that was me in eyes of all ..STRONG! ..

i personally alwasy thought i am a positive thinker! think of half full glass rathe rthan half empty.. i always said and still beleive that in most difficult times and in time of happiness also, one shoudl always go to god and pray to him n he/she will never feel low or sad..that is pray with full of faith and emaan to god..

now i dont knw what changed! coz it is same me who is feelign sad for one reason or the other! although i keep praying! but honestly maybe not as before..

My mother keeps tellign me: u changed n ur tempoer is too high and u dont need a reason to explode!
My sis ..she is the reason for me feeling so fedup of this life! belive or not! thu she love sme alot ,,but she is very short tempord person..and she explodes on me on anything i might say! or dont ..yesterday i asked her: what? ..coz i felt liek a question on her face ..she replied with a surrprised look at my question n said : nothing! n left me! n went to room ..

mama also felt the awkwardness but offcourse said nothing ..

my son is my life n my reason to smile.. my husboo is my reason to think positive..my parents r my reason to keep fighting the depression n do what is right .. but am scared that i reach a stage where no reason would affect on me except my contineous fights with my sis ,, for no reason,, leading to loosing all my life ..

may god forgive me for feeling so depressed ,,
