What is wrong me?

The first month after my brother's death I had lost 10 pounds. I kind of just chalked it up to the grief. It had crossed my mind several times that maybe I was losing weight because there was something physically wrong with me. They say sudden weight loss can be a sign of a problem.
The beginning of December I had gone to my family doctor to discuss anxiety medication. She gave me 2 kinds. One was to take daily to even out certain hormone levels and the other one was if I was feeling anxious I could take it for immediate relief. So one night I started the first one and about 1/2 hour later I felt like something was "caught" in my throat. I thought maybe the pill hadn't gone the whole was down my throat and was stuck. The feeling persisted for weeks and left me feeling very anxious. So anxious that I went back to the doctor. She sent me to a specialist who put a tube down my throat to do some "searching." It was very uncomfortable and gagging. He didn't see anything so he sent me to the hospital several weeks later. (Sorry, mom. I never told you about this. You guessed it- I didn't want to worry my parents). At the hospital, I had to drink this chalky, white solution while they took "live" xrays of my throat, esophagas and stomach to see if they saw anything obstructing. Nothing. Now I truly thought I was crazy. Something certainly felt wrong. This doctor wanted to send me to a gastroenterologist. I had had enough. I'll just live with it. I didn't have time for these appointments or the building medical expenses. I still have this feeling to this day. Some days it's worse than others. I have come to believe that this feeling in my throat is the result of anxiety. Anxiety doesn't just affect us emotionally, mentally and spiritually. It also affects us physically. I've talked to some people who have had that "closed throat" feeling and agree that it's the result of anxiety. Why doesn't the Lord just bring peace to my mind and my heart?
