5 more months, isn't much longer. At least you'll have that degree. I wouldn't make a leap into graphic design until fully earning a sustainable income that gives you freedoms and independence that money gives. It's kind of your bf to support you, at the same time it sounds like it could lead to complacency and could wind up feeling like entrapment despite how well you get along. Who knows maybe the stress of the job won't feel so suffocating as your worries?
