Its very easy to loose insight and focus on your goals to recover from an eating disorder. The subject at hand appears like a mountain that needs to be conqured. You feel fatigued already, and you start to question whether its really worth it... Well the answer is a definute yes. Even if it means that you have to spend a few years to get to a place where you are safe and mintanining a substancial amount of good physical and mental health. It is worth it as you will be able to have one less dillema (a huge problem that we know eating disorders are) that is not shadowing your life. I was browsing on somethingfishy.org, and believe you may benefit from the following advice:
A Glass That's Half-Full:
Constantly thinking "I can't do it" will set you up for something called "self-fulfilled prophecy", which means you predict and carry out your own future. You do have the ability to create your own success. If you are constantly thinking negatively about yourself and what you need to do, you only make it all the harder a task... and it becomes all the easier to just give in to your negative thinking. Being a negative thinker may seem "natural", but learning to give yourself credit, to look for the positives in yourself, and to say "I can do this" is an essential part of recovery.
Affirmations can help. Motivational exercises/games can help. Doing a gratitude list each day ("Today I'm thankful for [fill in the blanks]" -- it can be as simple as "I'm thankful I made it through today" or "I'm thankful for supportive friends"). Asking those you love and trust to give you a different (healthier) perspective can help. Surrounding yourself with supportive people can help. Something as simple as a bumper sticker on the ceiling above your bed that says "I CAN DO IT" can help. Find creative ways to be your own cheerleader, and to ask for reassurance when you're having a hard time.
