sister,what is the basis of the loss of iman? is it related to belief or to gender problems e.t.c. sister,I would highly recommend that you listen to the audio lectures on this site- www.yunuspatel.co.za Also,remember that Allah forgives every sin except shirk.So safeguard yourself against shirk first and foremost.Also sister,if you are of marriagable age and you not married,than find a good muslim husband of good tempremant.It would go a long way. May Allah Guide and Help us all.Aameen was salam
