Am I having anxiety attacks? Why?

I have lived with this for many years. It actually badly affected the exquisite pleasure of raising our two daughters: I felt something terrible would happen to her nearly all the time (especially with our firstborn). I still worry about them both but only in a more normal way now.
I have had similar feelings of anxiety about going bankrupt, losing all our money etc.

It is a lot less now because of age and experience (so far, none of it has happened). Maybe its a deep down insecurity?

You are having panic attacks. They don't need a trigger.

When you are stressed during the week relax all your muscles and then you wont have them again. If you have trauma in your past then EMDR therapy can help.

I am experiencing the same thing and I don't know what to do. I feel as if I am losing my mind.

Not sure but meds and therapy help tremendously.

You might want to see a therapist to work that out. They help in these situations.
