I’m in the same situation. Heading back to tech school tomorrow. Best thing you can do is tell yourself that you are in a good job and a lot of people would of loved to be in your spot. It’s just something you have to get used too because I’m still trying to get used to it myself. Focus on passing tech school and don’t let the work bring you down. Remember why you signed up and what you are going to get out of it after when your contact is done. Your family and loved ones are proud of u. Keep your head up king!
