I am sorry I know what you mean. It can be a constant sometimes. We can make ourselves feel so many things or some symptoms can escalate. I am going thru challenging times lately and sometimes I almost go into an anxiety attack. Us HA sufferers really do suffer. Yet sometimes we feel what we feel, we know we are feeling it and we get checked out and all ok. I am having a test done this morning. I pray I can get through my morning without attack. Hold your head up and keep on keeping on.
