Boiling with Jealousy

Ok so is going to sound horrible and I feel so selfish. I work at mcdonalds and have for about a year. Ijust finished my first year of college. My boyfriend also worked with me and he just finished his second year at college. Well he just got this great opportunity to work at an IT job on campus. I am sooo beyond happy for him and i think its great. So he quit mcds. And i cant help but fucking boil over with jealousy every time he talks about his job. I dont let him know, i just constantly tell him how proud i am and how happy i am for him. But inside i want to cry my eyes out because i hate my job and cant find another. I want to be happier for him than i am jealous but its consuming me. Ive never wanted a new job before now. How can i quit thinking like an asshole??
