i am a muslim girl and 20 years old. unfortunately i have been doing Masturbation since i was about 10 or 12. at first i didn't know it is a wrong thing to be done but when i got to know that i was doing it for 2 or 3 years and couldn't stop it. it was 2years ago that i found out that this deed is forbidden in islam too. i have tried to stop it for many times but failed. once i didn't do it for 7months but again... . the point about me is that sometimes i do it even just a few hours after saying my prayers... i really don't know what to do, can you help me please?
