Think back to what you went through to get into Pharmacy. The nerve wracking interviews, horrible science A-levels and endless revision.
As students we go through a lot and a lot of people like to brush it off as just hormones or temporary mood swings. I think you should confide in someone with your outside issues and find a solution because they seem to be the main cause on what's dragging you down.
If you feel lazy, kick yourself and understand that you have student debt to pay off soon for this course, you need to embrace every second of it, otherwise it's all just a waste. You're halfway there, don't give up!
