I'm so sorry for what you're feeling. I came from the polar opposite of where I grew up and still have a fairytale family chock full of support. While this is great in many ways, it also adds a layer of burden from expectations that the big family places. I am literally pulled in every direction from my family and expected to do everything for everyone. I love them very much but sometimes having a big and close family also can create some problems. Anything your going through the whole family will know about in 2 seconds - you have that many more people in your business and trying to please.
Again, I so appreciate having them in my life but please know that it's not as glamorous as it sounds. What people often talk of and display as happiness that we get envious of, have their own set of problems.
