Take a risk or suffer?

Hey guys, Im wanting some advice on my current dilemma. I work for a telecommunications company in the UK. I am studying Makeup Artistry for Fashion, TV and Film at university so I work there part time. The hours are great, the money is great and the people are great. Only downside is, I hate the job. I am unhappy there and I wake up every morning not wanting to go. I have recently been put on anxiety medication however Im not 100% sure this is down to my job, maybe other things going on in life. But working there, sure doesnt help me.
I have the opportunity for a Makeup Counter job, its a temporary ongoing role. At least 3 shifts a week, the hours are retail hours so not amazing. The money is pretty much the same. However after Christmas, I have been told they are usually quieter but will still try to give shifts.
I have rent to pay and my car insurance which is very important. So Im unsure on what to do. Do I take the risk and get my foot in the door with what I want to be doing with my career or do I stay at a permenant job where Im unhappy?
I am stuck on this right now and really need outsiders thoughts and opinions. Please comment below. Much appreciated.
