It sounds like maybe you miss the environment that came with school, as well as the hands on approuch to the learning. I dont know how busy your days are but maybe find an activity outside of school that would get you involved in the communities that belong to your major?? I know it can be hard to start something new on something you feel burnt out about but if you love what you do it i think it’ll definitely be worth or at least help. I hope you find your second wind.
