5 months ago I had a panic attack caused by a fear of not being able to breath due to a sinus problem . It got so bad I ended up in emergency , my heart was beating out of my chest .,and I was sure I was having a heart attack. As it turned out my heart was ok but since then my life has changed. Im now on adavan for anxity and taking lamictal for three months , but not getting much better. I haven t had another panic attack since the event but live in fear of it and many other things. Anything that has to do with breathing freaks me out , I can be fine as long as Im busy but if I sit down and start thinking about my breathing I all of a sudden start breathing harder and it is very stressful. I also have trouble sleeping and have thoughts of not ever getting better . I get to the point of wanting to give up , I also have problem with my back that is present all the time im sitting which dosnt help. Im becoming withdrawn and don t want to go out and do anything . What can I do .
