Struggling college student

Options
Hey there. I'm Kelsey and I'm studying to be a Social Worker. I recently moved out of my parents house and bought a home with my Fiance. Living on our own, and having less money has lead to me buying unhealthy foods. Also, most of my time is spent working or studying so I haven't been working out as I should.

I recently gained 20 lbs and have been overwhelmed with guilt and disgust in myself.

I'm here to work my butt off and lose 30 lbs!

If anyone has any tips for a struggling college student who works full time, please let me know!
