You really have to go with your heart on this one i am afraid, you can talk it through with others but you have to make the decision, you don't have to make a rush decision, i did an access course 4 years ago and then decided to take a temp job that turned into 3 years, i really enjoyed it but decided i wanted to go to uni to study education, i left the job and i am a full time student, money is thin on the ground but i wouldn't change a thing at the moment, i don't regret not going to uni 4 years ago as the job i did gave me confidence and that will be with me forever. You will make a decison soon and you'll know it was the right one! Good luck
