Am A Female 32. Have Suffered With Depression With Depression,

am a female 32. Have suffered with depression with depression, anxiety and IBS for over 10+ years. Since August I was starting to get heart palpitations and pain ask over my body, was sent up the hospital, had a load of tests done and all back clear. Was given 150mg of propananol and sertraline. These don't seem to be helping and had awful pain yesterday that I went up the hospital again yesterday any tests came back clear. Everyone keeps saying it is anxiety but the last week or so I have felt mentally better than I have in ages and I don't believe I am anxious at the moment. The pain is really effecting me day to day and I need it sorted. Please help
