M25, xray, cbc, ecg all normal. everyday i get anxiety attacks when i get tired easily, feel queezy and breathless when sitting or laying down for prolonged periods. can my acid reflux be causing this or is it psychological? what other tests can iget?

Your acid reflux could be causing some of these symptoms but you are not likely to have significant reflux when sitting up. You should see a GI doctor to determine how severe your reflux is-you can have a pH probe placed and then you will know if you are having significant reflux even when you are sitting. If the etiology of your symptoms is reflux, it will need to be treated by GI. Good luck!
