Just a little rant

My fiance has a labor intensive job, he's a technician at a Dodge dealership. I am a senior in highschool and I also work a part time job at my local bjs deli. My fiance always has to one up me and say that he has it worse than me and it upsets me. I get that his job isn't just sitting at a desk and he has to lift tires and use tools all day in a shop with no ac but he only has to be out from 7 to 5. I on the other hand am at school from 7 to 3 taking honors and AP classes and get home with 20 minutes to get ready for work and then I get home around 930pm just to shower do homework and get ready to do it all over again the next day. And even though it's a part time job I still work 5 days a week and only get one day off during the school week. I'm exhausted and he thinks because I don't work in a shop and I sit at a desk and then slice meat I shouldn't be.
