So, for a while I've been using a binder that I made myself using an old pair of my mom's control top pants. I was extremely sick a while ago, and since it was untreated for months, I was hacking and coughing very badly (falling to the ground in hacking fits). One day in class I had another coughing fit when I felt a crack, and a horrible pain in my chest. This happened a few more times (I have a very high pain threshold) until I could hardly sit because I was in so much pain. I continued binding, and stopped when I got better. I started binding again recently and it was all fine and well until yesterday. I came home from school, changed clothes and sat on my bed. All of a sudden I got a horrible, tight feeling in my chest and it was extremely hard to breathe. I immediately ran to the bathroom, and took off the binder. There was an obvious line of where the binder sat, and I now have a few bruises and a massive blister on my shoulder from it. All evening yesterday I felt as if I'd been crushed or something. I posted on tumblr, as I was very frustrated at my situation (getting unbearable dysphoria recently, can't bear going without my binder at all).
I came home from school, and found a reply to my post on tumblr from someone I've never spoke to before. They offered to pay for a binder or put the money for it in my paypal (which I don't have, considering I'm 13)... I declined, but said I may take up the offer later. Is this suspicious, or should I trust them? I feel like it is suspicious, so I'm looking forward to hear what some more experienced trans folk think.
