I got into hunting late in life when I move to the US from the UK. I remember the feeling of killing something for the first time. It does get easier. Now, if I can't get a humane kill shot, I don't shoot.
Another option for you might be photography. It's a great companion hobby for every hunter. You can hunt all year long and you use almost all the same skills. The thrill is in the chase, and the chase is exactly the same. You just shoot with a different weapon.
