I think you made a great move to quit and just focus on your studies, Dani. School is stressful. Some people can do both and even throw in extra classes or whatever, while some can take a couple classes per semester where it is permitted. But everyone is different. Making comparisons wouldn't help anyway. Go at your pace; do what you can manage so you won't be overwhelmed all the time. Sounds like you're doing that already, which is good. You're on your time, so you should be in control of how much of that time gets dedicated to each thing in your life. So well done
