Hello Nisey!
First off, Congratulations on your decision. That is the hardest decision of this entire process you have to take. Secondly, even though your weight-loss was not documented from the beginning you have to be proud of yourself because that is a great start to a new you!
I am like you, I begin my liquid diet starting Monday and am both nervous but excited. I have been heavy so long I just cannot wait to be thinner, healthy, and more active again.
I am going to recommend to you what Ralph (dancinbr) has mentioned to me in previous posts. His advice is to write down everything now of the things that you cannot do, what challenges you, and what you feel like. Also include the size of your clothing, your weight, and anything else you want to "remember" of how horrible you feel now.
Next reflect on how you are feeling as your weight loss started to come off (this is from when you went to the doctor until now). You can write down things like foods you avoided, what obstacles you came across, but most importantly highlight on the areas where you started noticing how much better you are feeling. In this "positive side" you should take note of how clothes are fitting on you, how much smaller you now can eat, drinking more water, etc...
Then as you begin the liquid diet keep writing in your journal of how you are beginning to feel. Reflect if you are having more energy, feeling good, how much weight you are losing, clothes feel, etc.
Like Ralph expressed to me before, its your journal so you can write whatever you want to in it, but keep in mind in the beginning the "negative side" are the things that limited you from enjoying your life before you were given the opportunity to become the new you which ultimately is the "positive side." Eventually you will see how things will transition from all negatives to mostly positives.
A good example for me is (my negative) I can barely breathe especially from walking out my door to my car. Or, climbing stairs is extremely hard on my lungs I will avoid them at all costs. I am looking to the day all my negatives to be my positives and through everyones support I know this can happen.
I know I am probably babbling, but keep up the good work.
