I was diagnosed with anxiety about three weeks ago, and this has been the toughest three weeks of my life. I'm only twenty one, so this is terrifying for me. It came out of the blue, and I just don't know whay to do. I have Xanax, Paxil and am on medicine for acid reflux as well. I just get this constant pressure towards the middle of my chest, and throat, almost as if it switches off. My heart also feels weak, and it's hard for me to breathe. I've been to the ER and seen my Doctor twice in three weeks, and they have all said I am fine. It's just scary, and it would really help/comfort me to know someone else has been through this. I'm just in constant fear, it's bad. I need some techniques, or something...If you have a moment, anyone, please. It would help to much, I'm just so scared all the time and I feel so weak. I would really appreciate it, please and thank you.
