New work, New life, need guidance

Hi redditors, I'm an IT engineer [27M] and I recently got a work far from my hometown which I'm very happy about it as I'm eager to this new life far away from my past and home. Almost half of my salary will go to rent and bills, my schedule is 2 days from 8 am to 8pm and 2 nights from 8pm->am and 4 days rest afterward . I make 1 hour to get to work. I never had such rythm before and I'm lost on how to share my rest time, my food (i'm below decent at cooking) and also I'd like to include workout in my schedule . Thanks
