FNP program

Hello nurses.

I am An RN who graduated in 2012. Nursing has always been tough since I started, I was always against going back to school for NP program because of my poor decision making( that is my feeling) but I had an ambiance to go back to school for graduate nursing program other than NP. I always think I have poor decision making skills and high stress/anxiety level. I still feel I am weak as far as nursing experience goes. Now I applied for nursing FNP program and got accepted. I am totally confused if I shoudl go for it or wait. If this is the right path for me or not. Would that make me more anxious as far as the job goes in the future. I am also getting married in the summer, and the school will start in September. I don't know if that is the right time for me to pursue this program. I am totally confused. Any help?
