ANSWER:
This is satan messing with your mind to make you go back to sinning and would not stop until you commit other bigger sins.
These are all waswas from Satan to depress and sadden you. You must ignore these and never contemplate on these thoughts and engage yourself in constructive, halal activities and always keep your mouth moist with the remembrance of Allah. Have complete reliance and faith in Allah and pray & hope for the best as Allah is as His servant thinks of Him.
