Currently, I am a student at an accredited school for RVT in OK.I just graduated high school in the last year and I tried to find something to do. I am in my first semester and I can tell you it will be a hard field in which you must be ready to keep up your education and constantly adapt to situations. It requires so much from you just in school. I would recommend getting your basics while looking into some programs.
I have the same worries about supporting a family on this salary one day, especially since my husband is trying to go for a teaching degree, which teachers are some of the lowest paid jobs in OK.
I have been looking around this site as well and it seems like Vet Tech is just a difficult job and either you will love it or hate it. I hear that some states are trying hard to change the rules for RVT, LVT, and CVTs to help the salary and way that the employees are treated. Gives me hope that it might be better soon.
Anyways, sorry for babbling, but I hope you can figure out what you want to do
