Hummingbird, I am sorry to hear about your pain but yes, there is hope. I had not always had anxiety either but I had a breakdown a number of years ago that started with intense, persistent anxiety like you are describing. Just like you, I remember desperately wanting things to go back to where they were 'before' the anxiety started.
It took time and effort but I am much better now than I was back then. It is good that you are still out in the world, doing things you always do like riding the bus and going to school even though it is difficult. I took some time off work when I was at my worst but I went back even though I was not comfortable (that is an understatement).
Keep talking about it and keep coming back.
