Help - big jitters, please tell me yours was worth it?

1 week away from TT. Nerves kicking in big time, even though I have wanted this for so so long! I have 3 children and my nerves are more about the morale issue that I am doing something for vanity and there is a risk. I am also worried about the healing but I am actually quite good with pain. Every time I get bad thoughts about it I picture how I feel in clothes, on the beach etc and then how I will feel after. Please tell me yours was worth it?
