I have had what you are discribing and a lot worse. believe me.
You say you need us to tell you what you already know. Well here it is:
You need help.
Medication and therapy combined. You need to want
to get better, You need to commit
and you need to stick with your decision.
That's all. You will get better
but you have to have patience .
Exercise and other physical activities help as do new hobbies and interests.
I am a survivor of very crippling panic attacks which I have had for the last four years. I am now 46 and I am enjoying a new lease of life.
It can be done, you can get better. Do not be scared just take the plunge. Do not waste time and energy thinking. Just do it.
God bless you
