If what you are suffering from is an anxiety disorder, experiencing times that we feel we are going crazy is not uncommon. This is nothing more than another symptom, protective reaction, of the panic disorder, itself.
Having close friends and family is indeed a Godsend, but our anxiety can also use these relationships as a dependent crutch, in which we can feel that we can't function without them. When this occurs, this aspect of the relationship is not healthy.
Lorraine, there are very positive treatments available for anxiety/panic disorders, and I can certainly vouch for that. I see a psychiatrist for my mental health needs. Psychiatrists are medical doctors who can provide you with a diagnosis, prescribe medication, and develop a treatment plan specific to your needs. I am on anti-depressant therapy. I also see a psychologist, who is my therapist, and she is teaching me cognitive behavioral therapy (CBT). Both the medication and therapy have turned my life around in the last six months.
I highly suggest that you seek out professional help, as I did.
The very best to you, Lorraine!... Chuck
