Welcome to the returning player's club. There are a lot of us here and there is a lot of advice (some good, some not-so-good) to be found if you spend some time browsing the threads. Just remember, it could be worse. One of our comeback players was off for 53 years. But, we just think of it as a long series of rests between notes. While you're shopping, buy several trumpets. That's what I did (started with only one) and it has really made my comeback much faster than it would have been otherwise.
