Skin related problem. Gynaecologists.

Hi Mam/Sir I have more darkness on my vagina and in between thighs . Before i don't have any darkness after using pads only i got some darkness . I tried to remove that darkness by using more home remedies and i used namya intimate lightning serum but those all increased my darkness. From 7 years onwards i am suffering with problem, i can't share this problem to anyone. Now my age 23, i think next year my parents will do marriage to me. With these problem i can't do marry anyone. I hate myself, I am crying inside everyday , I lost my skin tone , I lost my confidence, i didn't concentrate on my studies from 7years , now in job also. I have only two options one is to solve my problem before marriage second one is suicide . Please tell any solution my problem. I am asking to all gynaecologists.
