Hadith question

Q: I heard of a hadeeth, I can't exactly remember but it mentions that in Judgement day, Allah will put the sins of a believers onto a non muslim and that the punishment for the believer would be replaced by a non muslims. Is there any Hadeeth of this sort and if there is, would you tell me what this specifically means, any reliable interpretations of this hadeeth?

Waswasahs

Q: I have been having a problem for very long now, like a year. Its the  problem of waswasa. I get these thoughts of kufr and I can't stop it. I know we are supposed to ignore it but the shaytaan overtakes me. I know there is no god but Allah and this deen truly is the haq but shaytaan gives me waswasa.I have had enough now. I am always depressed. Is there any way to stop this?

Accusing somone of putting sihr and jadu on oneself

Q: I recently found out my dad did some sort of magic so that I would marry his choice. I since have been divorced. I have a child too. I found my
dad did this as I asked an aalim, nothing is going right for me, studies, health, rishta etc. The aalim told me to hold a blank sheet of paper whilst he
recited quran, and on the sheet of paper came the images of those who did magic on me and ruined my life, my uncle, my dad, my ex husband, my dads aunty. I need someting to read to cure this bundish.
