assalaamu 'alaykum my dear sister, It is not Allah ta'ala's adhaab on you. Now why would he punish you when you have decided to repent and turn to Him? Think about it. If anyone has to lose anything, it is Shaytaan. He knows you're turning to Allah and he knows that Allah will forgive all your past in a moment so he's attacking you with these whispers. Ignore them like you would ignore an unwanted obnoxious guest and he will go away insha Allah.
