I feel that way too. It’s so hard to tell anyone about what’s going on because of worry that it could be too heavy to put on them. I mentioned this to my friend last night. I said that I was really emotional over the weekend and I didn’t call because it might be too much to deal with.
He said that no, that’s what friends are for and it’s okay. Which, if I consider the reverse situation, then I would definitely want to be there for him.
Of course I can’t say if that’s true for your contacts. If there is someone you can trust, it is possible to ask ahead of time, like, “hey I am dealing with something serious, but I don’t want to burden you if there’s already too much on your plate.” That gives them the choice, and I doubt they would say no, because it is the nature of human beings to want to help each other.
