blinded by emotions

I really hope that my emotions don't blind me. I am not going to lie, I am scared. I'm scared for my life. But if i never take this risk, I will never know. The hardest part is the fact that I value my close friends and family's opinions a lot, and I basically have no support in this decision. How is it that for something that I want so badly, is so looked down upon by the ones closest to me. Am i really being blinded by my emotions?
