How to get life together

Hey all I have started my college and I’m really overwhelmed and clueless about how to manage it now its been almost a month and i still haven’t figured out how to balance my personal life with academics. Other than studies weight loss is also a goal that i look forward to achieve but i find it very difficult because while studying i do get the urge to munch on something and i can’t resist it
I just want to be a better version of myself but i don’t know how to🫠
I am currently doing bachelor’s in psychology and if possible also suggest any apps website or even telegram channel that could provide useful notes or references
