Somewhere in my heart I am getting a feeling that out of my fear to lose her and my anger to see her going hysterical made me slap her to get her back to senses. I'm not able to make it clear. Darr lagta hai kahin anger toh nahi tha itna ki maa ko maar diya. Although her veins of neck and temple got swelled which could have led to haemorrhage if she wasn't stopped to scream. I'm not able to forgive myself. I'm seeing my darling innocent mother and I feel bad for my heinous deed

Hurting urself is also ghunnah, so don't put urself in more trouble. If logically u don't come out from this situation then, shaitan will lead u to other ghunnah. Control yourself and be normal. Things happen in life. Your mother needs you, so be positive and calm
