Things that worked for me in the beginning (This is when I wasn't eating or leaving my house. I was skipping work and spending my time balled up in a chair, crying and thinking about how terrified I was.)

I think the BIGGEST thing for me was setting small goals and working on them until they were met. It gave me a sense of accomplishment, even though the tasks were not all that amazing. It allowed me to start believing that I was the one in control, that I could overtake the anxiety and reclaim my life.

Things I did:
Worked on counting backwards from 300 - ALL the way through without stopping to worry about how scared I was.

Forced myself to get up and do a load of laundry, clean out a drawer, brush my cat, reorganized a bookshelf, etc. I would do it when the urge to sit and cry seemed impossible to overcome.

Made lists of ways to comfort myself while doing scary things. I was TERRIFIED to drive. So I made a list of things I could take with me in the car - a blanket, a bottle of water, gum, baby carrots, bought some new CDs, etc.

I used to spend a lot of time working on my quote list. I would scour the internet for quotes that I liked - things about facing fear, having courage, finding happiness. I'd copy and paste them into a word document. I loved organizing the list & honestly, sitting and reading motivational quotes has an effect on you. It always made me feel better.

I read a TON about anxiety, panic disorder, panic attacks, anxiety disorders, CBT, etc etc. Becoming educated helped take away the fear of the unknown. Understanding what was happening really helped.

Part of it was telling myself that I'd have to start doing normal things if I wanted to feel normal. So SO hard, but so SO worth it.
