16. So, unless you are really smart, you have 2 more years of high school before you can get into university and study to be a vet, a 4 year program unless you were going for Vet Tech at college which still may be 3 years. In either case, you have a minimum of 5 more years of schooling. This will be difficult to do as well as operate a household and hold down a job.
Given your spelling and grammar, I don't see a lot of money behind you to make life easy. I suggest that you should wait until you have finished school, including college, and started a job before you get married and take on the challenges of a family.
If it is raging hormones, find a way to deal with them safely.
