There are lots of people who have come into my life, normally because we both have ME; but when they get better they tend to fade away, moving on to doing "normal" things and not having the time to stay in touch. It's always really hard, especially because not only are you hurt that they have abandoned you; but it reinforces that you're still ill and that another person has got better.
I always wonder where they are and what they're up to; but in a way it's probably a good thing because it would be harder seeing them living a normal life while mine is still so restricted.
Sometimes it doesn't matter how hard you try to keep a friendship going, it just won't. I've learnt that most friendships have a time limit, that you learn from each other and grow, sometimes together sometimes apart. It's sad; but you have to let go of the old to make way for the new.
