You sound so much like me that while reading your post I started to think I wrote it. lol.
I have suffered from anxiety since the age of 20 and Im 36 now. I too have anxiety and panic so bad that I rarely leave the house anymore. It is troubling to say the least. And I have a child so I know how guilty you feel that you cannot concentrate on your kids like you would like to. Its a never ending cycle and very draining. (Im lucky if I get 4 hours of good sleep a night!)
The only thing I can tell you is to keep trying different meds through your doctor and start seeing a therapist. Someone who specializes in anxiety and panic disorders. Once you find the right meds and are on them enough time for your body to get used to them, you will feel a lot better. I am just starting a new med myself. I tend to go off every now and again in the hopes that I can function without them, but then the anxiety hits me like a ton of bricks and I have to start all over.

I do the square breathing a lot. I watch TV at night because it helps take my mind off things. I write in a journal when I have a symptom or attack so I can keep track of all of it and maybe see a pattern. (One day I wrote in that journal about 50 times and realized I needed to keep myself busier, even if I didn't feel like it!)

I hope that helps you some and if anything just knowing that someone else knows EXACTLY what your going thru. PM me anytime if you need to talk or have any questions. It helps to have people to lean on....
