my family is going to florida. we live in texas, and they are going in our suv so as you know it's pretty long from texas to florida. thousand miles in a trip. and i get fustrated when we are traveling, my legs start to feel weak and get bored, i don't know whether i should go. they are going for 3 weeks. should i go? if i don't go i will stay here alone in texas by myself.

This is really something you should discuss with your family and not with strangers on the internet.
