Hi, Azfrostqn! Welcome to the board.
A good place to start is with Dr. McDougall's free online program here:

Read through it and start thinking about how you could begin implementing it in your life.
When my wife and I started McDougalling, there were basically two things we had to figure out: 1) how to get rid of the unhealthy food we had and were eating at the time, and 2) how and where to acquire healthy food that would support our health and help us achieve our goals.
We found that it was important for us to get all the "trigger" foods that tempted us to overeat out of our house. Our house had to become a "safe" zone with nothing to derail us or make sticking with the program more difficult. That meant getting rid of all the chips, sauces, meats, etc., etc. We threw some away and gave some away (and postponed beginning so we could eat some of it, probably not the best choice in retrospect). It also meant stocking our cupboards with potatos and oatmeal and brown rice and veggies and fruit and all the healthy, unprocessed foods we enjoy.
Karen and I were lucky in that we started McDougalling together and were able to support each other. You didn't say anything about your living circumstances. It's easier if you have the support of your partner or roommate, but even if you don't, you can do this.
You don't have to do it all at once. Some people find it easier to ease into changes gradually while others prefer to go cold turkey. Do what works best for you. Take your time. Keep posting and reading here on the board. We're here for you.
