Ongoing symptoms

I am so frustrated and discouraged. For the past 5-6 weeks i lost my appetite, am nauseous, bloating, abdomen pain, been vomiting, lost about 20 pounds, heart rate is like 50-100 when laying down/sitting but can get up to like 140 when standing, very fatigued, i feel weak and out of it, always in some type of pain, etc. my labs are normal, my abdomen ct was normal just besides a small hiatal hernia and fatty liver, my mri of my head and back were normal, normal ekg and i guess “normal” 72 holter monitor even though it said i was tachycardic at times, stool sample for blood normal. Im at a loss and completely frustrated. I just want answers or a cure or something. Does anyone have any opinions?
