Stacie, I used to work in a creative industry, and after many years I decided it was time for a change. I did a little soul searching, and decided to combine my life-long interest in the medical field with my love for animals.
Veterinary medical work is very physical: restraining animals of varying sizes, risk of injury and getting bitten, lifting, holding, pushing, pulling, bending, reaching, cleaning, allergies, etc. All medical jobs have certain hazards, such as exposure to diseases and chemicals (you'll find out...). Maybe the hardest part of the job is "transitioning" very sick animals, which comes with the territory. And yet the personal rewards can be wonderful, when you feel good about helping animals and their human companions who entrust their care to you. The one thing this industry is not: M-F, 9-5. You may be able to work that schedule after getting a great job one day, but most jobs include weekends, and that is the truth.
You're right that everyone has issues in their job or professional industry. If you are curious, do a bit more research. Visit the library or bookstore, talk to your vet or the vet of friends/family pets, learn about the types of industry jobs and their requirements. It is not a high paying industry, and everyone starts at the entry-level.
If you decide that it's what you want to do, look into the educational programs, starting with your local community or junior colleges. Some distance learning programs are reasonably priced, but you have to find your own clinic or hospital to work in for the hands-on part of the program, and you have to be very self-disciplined. There is a lot of science stuff.
Look to your heart's desire for what will bring you the most personal satisfaction, whether that is helping others, making lots of money, gaining fame, or whatever. Only YOU can decide whether you "should do this or not".
