Don't leave bro. At least keep a small 100g with community fish. You will be loosing your mind dealing with school and work. You will need a tank at home to stare at to take the stress off.
working at a green house killed gardening for me for YEARS. Its been seven years and now I'm actually planning some DIY landscaping for next spring. WOW. You can never truely give up something you love but you have to part ways to realize what you love about it. Was the same for gardening and the first and second time I stopped keeping fish.
