Transferring universities

Hi,
I am in my first year at a university, I chose this university because I play basketball and I was recruited to this school to play here. I was very excited to move away from home and start a new life but I’m 5 months in and I can’t say that I have enjoyed myself at all. I am miserable all day and I don’t have a lot of time to socialize and have fun because basketball is so time consuming and physically and mentally draining. I love basketball so much but since I have moved here I have had no motivation to do it, I just look for reasons to hate it more and more. I miss my family and friends a lot and I have reached out to them a lot for help. I originally decided that I wanted to stick out the whole year and try my best, but I’ve hit a point where I don’t know why I would stay when I am this unhappy with my life. My parents are completely supportive of whatever I need to do to be happy. I have come up with backup plans to switch schools after Christmas where I would be closer to home and with my boyfriend as well. As of right now I have decided to leave, it is not worth staying and sacrificing happiness. Has anyone else been through something similar and transferred because of it?
