Stop stressing! You will have various options available to you, hopefully. Many of us went through what I like to call the "ramen noodle phase." You don't normally start out doing well!
Ways to nip it in the bud, right now:
1. keep a good relationship with your parents. It really helps to be able to stay at home from about 18-25, and saving up money!
2. if you buy a car, look for a good used model. I am 58, and have had only 4 cars, all of them used! A car is a mode of transportation. It is not necessary to get one to impress other people, unless you are a realtor or otherwise use it in your job.
3. Think about school. 4 yr degree? trade school? what? There are some employers who have tuition assistance programs (HEB?). If you can work full time, and go to school part time, it would take about 6 years. It's great to have others help in paying for it. Military option?
4. Watch your spending. Live within your means. Learn the difference between "wants" and "needs."
5. Learn about credit, interest rates, paying off loans, insurance, etc.
6. learn about disability insurance. It will pay part of your salary if you are unable to work. It is pretty inexpensive if purchased through an employer plan, or even on your own, if you are young and healthy.
7. start saving! Get the best interest you can for your money, while still being able to get to it if you need to. This is usually in money market accounts.
What does all this have to do with your question? Simple. I have known people who earned a 6-figure salary, but they were flat broke, living in their mansions, with their swimming pools, etc. So, a lot depends on lifestyle!
As you do your calculations, a good number to know is 2080. That is how many working hours are in a year. There are 4.3 weeks in a month. Remember to include money taken out for taxes. I don't know Weatherford. But, this website will help you get a more realistic picture of living expenses. I usually figure it takes at least $15/hr ($31,200 a year) to live on your own, IF you watch your money closely, and do not have a pet. Pets are extremely expensive! Unexpected expenses can set you back, so you want to learn to save. (car repairs, medical co-pays, etc).

I encourage you as you start out on your own to learn to keep records of your expenses, as it helps you to see where your money is going and where you can make changes in your spending. Having recently retired, with limited resources, it is what I do. I log each and every expense, even breaking down my grocery receipt by household, personal, food, tax. . . . The better habits you start out with, the easier it will be!
I hope this helps a little. Please check out the links - they provide a lot of useful information!
