You know, I would be worried too were I in your place, it's normal, and I believe good for your your mental health. Look at it this way, it's normal to experience appropriate emotions in appropriate situations, which is a very good thing, your not trying to fake it or repress your emotions. Now, what can you do to manage this fear? Tell yourself it's ok to feel and you'll continue to live your normal life too utill you get the diagnosis Do both, the mind is great at multi-tasking. And the more you talk about it with family and friends the less that gets bottled up and the better you'll feel. There's nothing you can do now, so why invest precious time and memories into that which you can not change. the alternative is to control what you can and accept this feeling for what it is. Temporary, transitory, and short term. And I hope with all my heart you get the news you want. I'll bet that's what your doing too.
Since I'm not the type of person who likes telling my problems to others, I always think of the many times when I worried and it turned out to be fine. Everything has a way of working itself out. I tell myself that I'm just a worry wart and that I need to stop it and think positive. Everyone handles things differently so I also agree with the other reviews about talking to someone who may be able to comfort you. Hang in there. I am confident that everything will be ok.
