First step. Take a deep breath! It will be ok. After the news has settled in, then perhaps go and speak with your family so you can get them on board, or at least get their support. If you can another option might be to hire a health coach, this will be someone that can be of support to you on your journey and help you out along the way.
Another thing will be to take it slowly. Unless you are having a medical crisis and your Dr says you have to drop everything at once. Try eliminating a couple of the foods you are supposed to get out of your diet, while adding in ones you are supposed to intake. If you do everything at once, it is less likely that it will be a life long change. As you adjust to those changes and then feel good about those, then move on by taking out the next couple of foods and adding in some others. The longer you go, the easier it will be - provided that you are still giving yourself foods that are truly going to nourish your body. Regardless of what your diet is, try to incorporate as many natural unprocessed foods as you can. Those are what will fill your body and provide nutrition.
Find ways to mentally take care of yourself as well. This may be different for everyone. Examples could be yoga, mediation, a walk out in nature, a massage, a manicure. Take some time out for you where you have something to do that is not focused on food and where you can feel good about yourself.
Change can happen! Find and utilize the tools so that you can be successful!
I have been there. I was very sickly as a late teen/early 20's. I had endometriosis, asthma, hypothyroid, and some chronic fatigue syndrome going on. The nutritionists wanted to stick me on $500-$600 in supplements. The drs didn't really know what to do for me - medicate me?? I knew I needed to make a change at that point and take the ball by the horns and help myself to get well. I flipped my diet around, cut out coffee first. At the time this was so difficult. I was truly a coffee junkie! I loved coffee,drank triple shot expressos daily, loved coffee beans, I could not get enough coffee. Nor did I feel like I could function without coffee. I got it out of my diet and now still all these years later, I don't miss it. I have plenty of natural energy and am able to get up and go without the stimulant. Next I cut out the white sugar, then onto white flour. As I was taking one thing out, I also incorporated fresh veggie juices into my lifestyle, then more home cooked meals, then more raw fruits & vegetables. it was a process of give & take. Nothing happens over night, at least not true lasting change. After around 6 months I felt great!
I will be ready to start taking some clients in march. If you are looking for a health coach and someone that can support you through lifestyle or diet changes. It is something I am familiar with I have been there myself and have also been there with my kids who have gone through a few themselves.
Change just requires determination, support and knowledge that you can do it!
