Struggling with studying

When I study my mind goes into two modes

1. pain avoidance If I study and then after sometime it goes into avoiding studying as it's painful for it so it subtely goes away from it as I don't let it go away directly Goes into daydreaming or makes me feel I am exhausted or don't have energy, sleepy, negative thoughts, worrying which I would not be if I was not studying

2. Threat scanning mode If I still somehow continue studying taking required breaks in between It goes I to this threat mode and makes the mind palette negative and everything that I think it starts thinking negative about it Starts catastrophisizing

Or starts thinking about existece and creates existential crisis which if I would not have been studying it would not have done so Or goes into ruminating about past or loss or unfairness

It has come to a point that I am thinking to stop studying and pursue something else even if I would earn way less but atleast wouldn't have been going through something where I am giving my time energy effort and money but nothing works my way

It has been years brain does like this Had it not been a problem I would have cracked my exams with gret marks I know thatcoz consciously I want to study and clear and move ahead but this survival mind just doesnt let's me at all and its this way from years. It just doesn't understands logic

For it since it gets to feel bad while studying it starts doing these things.
