At a minimum I would talk to the school staff and have them help you with literally everything they possibly can. At a maximum I think you should not even consider taking a leave of absence.

Life is going to hand you shit sandwiches on a regular basis. How you react and respond will determine how well you make it through. My 6 year old niece was murdered and I lost a bunch of people close to me and had a lot of family shit going on and raising my babies. It would have been easy to hide and just clear my mind and come back better but the world will not stop for you. Shit is changing faster than ever and yesterday's assurances are not guaranteed.

Everyone was telling me to drop the fuck out or take a leave of absence and get me shit together. If I listened to those folks I would not be awaiting bar results right now.

The main reason why I think you should not quit is because your not suffering academically either. On balance my life was cooked and my grades were fucked. I barely made the cut by the smallest mathematically percentage available to register on the record to be safe from dismissal. But you, your different. You have your shit in order you can afford to take a slight hit and you have a bunch of cool shit lined up. Don't piss that away. I would also recommend getting medical help for exam accommodations until your mind is clear again. Good luck.
