Winston Churchill once said, "Failure isn't fatal, and success isn't permanent."
Success is truly what you make of it; find and use your own standards and goals in knowing what you know now about yourself to accept what it is important to you in order to gauge how you are doing and what it is you are trying to achieve. Count any success towards meeting your goals as a your blessing, because you know what you have achieved and are steps to achieve what you want in the future.

Goals change over time as does our drive, what once was important may change, that is good; also in dealing with MH, those priorities become part of our goals and have their own set of goals as well to help us get from one point to another. Realistic expectations come with time and you will find that common ground as you start back; never lose sight of the dream as you need that ultimate goal to set your sights on, but needing to also set goals to get done on a daily basis the task at hand to accomplish it. You can do it!

Just believe you can and listen to what is going on with you as you move forward to work at a good pace for the workload, and remember to relax and have some fun too; it is all a matter of finding the right balance for you. Best wishes as you move forward, good luck!
