yay for you too!
As for your therapist.. those letters mean that she is a licensed social worker (which is very similar to a counselor).
Congrats on making it to the grocery store! YOU GO GIRL! That in and of itself is a huge accomplishment!
As for walking the dog, it sounds like you've devised a great plan. You just gotta stick to it, and take your time. Its best to gradually desensitize yourself, which it sounds like you're doing. If you can't do 1/2 an hour.. 10 minutes is perfectly fine. Its way better than not doing it at all. The half an hour was just an example, but its great that you are able to recognize that that would be too much for you. If you started out too strong, it would make it that much easier to give up. Half the battle is being able to recognize that your fears are irrational and recognizing what you really can and can't do. So i'm proud of you that you were able to recognize that 10 minutes is where you need to start.
As for your quotes.. print those out and carry them with you. Think about them whenever you start to feel scared. They can become your mantra and really distract you .. similar to how thinking about pheobe from friends can really help as well! (btw I love pheobe too)
As for thinking people might think you are stupid.. often we are much harder on ourselves than others are. I bet once people get to know you they'll love you and realize what a great friend you are. Your hubby did, and I'm sure these people will too. I know it will be hard, but you gave the perfect example- you'll never know until you try- and keep in mind your experiences as a child. you may dread going and become anxious about it, but in the end you might really have a fabulous time. If not, you leave, but you leave knowing that you at least put yourself out there and gave it a shot.
You're well on your way girl! Keep us updated when you make any plans, use REI, or have any accomplishments. No matter how small they are, they are still two steps forward. Remember- baby steps!
