I'm new to this site. Hope all is doing well. I'm 35 year old female who has been dealing with what I've been told is anxiety. It suddenly came on one day out of the blue. Can that really happen? Why? I have not been able to find my triggers. I have made numerous doctors/ hospital trips thinking I'm dying. I have nausea, tremors, neck/upper back pain, tension, leg weakness, feeling faint, etc. I'm constantly noticing my pulse, breathing, muscle twitche, etc. is all this common? I need reassurance. I'm always googling symtoms trying to self-diagnose myself which is never good. My mind is constantly running. I cannot sleep, have lost appetite, etc. it's effecting my home life, work life, and social life. What can I do to change something if I don't know the triggers? I have noticed when I go to drive I feel fainty. Any suggestions would be appreciated.
