HI OP,
I read your post where you say you are 'anxious about everything'
I too am like this. If I have a problem I literally roll it round and round and round and round in my mind and cannot think or concentrate upon anything else. When that problem is sorted, I will move on to something else. If there are no problems to focus on, I will catastrophize that something horrendous is going to happen to someone I love. It is delusional.
there are the mental symptoms which go hand in hand with the physical symptoms , the panic attack the tight throat the churning stomach, the sh1ts, chest pains, hormonal changes which can lead to all sorts of things for me hair loss. Large bald patches in my hair brought about by anxiety of IMAGINED things.
I tried several things, medication, counselling, but SO FAR, I have found meditation to be the thing that works for me. I have begun to learn about Buddhism at a local meditation centre . it is very early days of trying this but so far I am finding I can get answers to questions such as how to deal with daily problems
sorry if this sound all hippyish, but I too have spent a long time trying to find answers and this, is so far, what works for me
