Would really like some help. Feel terrible and have many symptoms but

[Brent]

doctors tell me I'm fine? I have been to the doctor twice and he keeps telling me I am fine and my blood tests are normal. I know my own body well enough to know I'm not fine. For the last year I have had horrible pellet constipation and bloating. After dealing with that for a while I started having fatigue, loss of appetite, and chronic sinus problems. All the symptoms are just getting to much too handle and I have become somewhat depressed and have started having mild anxiety attacks. Does anyone here have any idea what could be wrong with me? It all seemed to start around the time I took minocycline but I don't know if that is related at all
