Protocol adherence vs weight goal

I have done the stop overeating and have reached the weight i had wanted. I am 5’4” and weight between 123-127 lbs depending on the time of day/month etc. now i want to push myself to 120 lbs by the end of 2018 and be done with weight issues and focus on my IG for 2019. However when i think about that goal weight i feel fear of failure. It seems so close yet so far. Also im not sure whether my goal should be that weight or as Brooke says- to stay comitted to the protocol all of the time and allow the weight to fall off instead of trying to get this done in the next 2 weeks. I am aware that i am indulging in confusion here but i am finding it difficult to come up with a believeable thought to hold onto and get this done and behind me.
Existing model
T- 120 lbs is hard. Maybe i should just focus on sticking to my protocol and decide that this is behind me
F- doubt, fear;
A-failing and giving up ahead of time
R- no further weight loss
Here is my intentional model
T- i have already lost a lot of weight; i can totally do this
F- comitted
A- stick to protocol, allow urges
R- weigh 120 lbs
