Worry as a Christian

I am a hypochondriac. Meaning I often worry about and fabricate symptoms that I experience. I think many things that go on with my body are medical events or conditions. Lately I have felt even worse about it because I feel like my worry distracts me from God. It is said that we should not worry but I don’t know how to stop. Sometimes I’ll feel better and can brush stuff off but other times I’m consumed with worry.
