Good on you for making this decision. It is natural to feel some apprehension...but stay strong in your resolve!
There's the old adage of 'you must walk before you can run'...right?
Well your comment about
being active made me think of this. Now you are in a tough spot...and the anxiety has got you in a cycle that needs to be broken. Your medication can facilitate this...but you have to do the basic and hard work first....
...you have to take those first unsteady steps. Then, you'll find yourself feeling less unsure, and you'll be off and running again.
Try to think of this as a temporary means to an end. You may not need to be on the anxiety meds for long term...maybe just long enough for you to get out of this cycle...and then your coping skills may suffice...
...but for now, they are a tool that will help you get off the starting block!
