Loosing faith in life

I am a female, thirty six years of age and i have been married for past fifteen years .mine was a love marriage
and the circumstances during my marriage were such that i have to choose either marriage or my family,i chose marriage.
but very soon i realized that my decision was wrong as i was ill treated by my in laws and even by my husband who remained
indifferent to my sufferings .. i was always very good in studies and i thought that may be if i get a job my sufferings would reduce.
so i asked my husband for permission for an advanced diploma and after completing it i could get a job ....in my job everyone thinks i am a very jolly and happy person
but in my heart i am very sad and distressed ,my husband doesnt care about me he ignores my emotional and physical needs i became distant from my family for him and now i feel i have become alone in this world i feel as if i have no one to talk to no one really cares about me ,my husband puts a lot of restrictions on me i am left with no free will he tries to subjugate me by saying negative things about me and by fault finding constantly,i am very passionate but he doesnt give me proper attention neither emotional nor physical
.....he always criticizes me even in front of his female subordinates ,at times i felt he is having affair outside but he used to tell me
that it is not so ,but there were few times i found a few vulgar and intimate messages in his cell phone,but then it so happened that one day i got a call
informing me about his being with a girl at some place i went there and caught him red handed i feel very ashamed and lost
i became very angry i didnt know what to do i came home and took sleeping pills later i was hospitalized for one week ....these days i have resumed my job
but i feel what do i have left for me in life ,that i am a total looser ,why i do not have such basic happiness in my life i have not done wrong to anyone then why has god done this to me
i always use to cry very easily and always was very sensitive to offenses .
these days i do not feel like doing anything i feel very humiliated and hopeless,
i keep on sitting where ever i am ,without doing any work i dont feel like doing anything no house keeping
no aspirations left in job advancements i dont feel like doing anything for my children even.i was very lively person but now i feel shattered and my confidence level is at the lowest.i feel like running away from all this to some far away place .

This is story of my friend she is disparately in need of remedy which can help her restore her mental balance
i hope what things i have mentioned are sufficient for the doctors to recommend a remedy if more details are
required i can ask and post,thank you.
