Well I think you need to stop focusing on the disorders and the outside negativity, and focus on your goal. The disorders, the outside people, they become sub-conscious excuses, crutches to stay the way you are. Just keep in mind how badly you want to achieve your goal and keep your mind set on it, it'll be worth it. Most importantly, don't push yourself to hard. If you do have disorders you should acknowledge them and work your exercise routine around them.
