How big is your comfort zone?

Lately, I've been doing things that completely out of my comfort zone. I admit that it felt great to get out from it for a while. Everything seems new to me and it's like a roller coaster ride. I'm having acrophobia and I hate getting on a plane. Sit beside the window of the plane can be worst for me. I felt like dying at first, my hands started to sweat, my foot cold as ice, my head is spinning and I can't breathe properly. I know I shouldn't let that conquered me. I'm still learning to handle it. Sometimes I pick a seat near the window and I felt good to see the clouds that almost similar to cotton candy. It was pink and white as if I was in a cotton candy heaven. I know it's lame but that's why I felt. Maybe it is the new way to manage the phobia. Who knows right? Okay, I had a dream last night. I'm not sure whether it was good or bad but it was about my crush. Seems like he asked me to go to the gym and lose weight. Yes, I know I'm fat. But I also having a plan to do the weight lose challenge between me and my sister. There's a person who keep asking me when will I lose weight, you look great if you are skinny and blah blah blah.. I know it's important to take care of physical appearance but let me focus one thing first, study. It's been a hell semester for me now. I'm having exams and soon going back to my hometown. The price for flight ticket is soaring high because of Eid this end of the month and that counts as holiday since it is a celebration. How big is my comfort zone? this question somewhat makes me think twice. Did I really thought about it? Or I just slowly expand the zone. Making friends might influenced our comfort zone. For instance, I'm such a timid person. Public speaking is a big no no for me but the more friends I had, the more braver I've gotten. This may sounds weird to you but it really happens on me. My comfort zone keep on expanding because of my surrounding and people. I basically live in a new city for the past 3 years. I'm grateful for this kind of experience. I did changed a lot. More independent, still struggling to manage my own financial (HAHA), failed to eat clean, closer to God, still into him and many more. The transformation is not only for physically but also mentally.
