Normal endoscopy , still symptoms

I had an endoscopy Tuesday as well as capsule bravo (waiting results from that). My Endo came back clear. However they didn't do a biopsy or other testing. I feel so invalidated because I'm still suffering. Where do I go from here? I've been on a bland diet, pantaprozole, carafate and famotodine since November and whenever I feel like I'm getting better it comes back. I don't know what to do
