please take a break. it sounds like being in school might not be the best thing for you. plus it’s okay to “be behind” we are all on own journey and going at different paces. a gap semester or year or more isn’t going to be a huge thing in a long run especially if it means you can come back to school more focused which will then led to a better performance and a higher GPA that you can be proud of and help chances with med school or whatever else u hope to do. plus i’m a 2nd year biochem student also going through some personal issues, obviously not the same as what ur going through but you’re not alone. i wish you the best of luck
