Aw, I'm really sorry you had this experience. I can see/read how much it's upset you. I can see that you are feeling unconsidered, which must be frustrating especially because of the time and effort you put into considering others.It is also okay about your family - no family is perfect and it is clear that you love them. It is also okay to feel upset.
It's hard for me to give you advice becuase I don't know your family, and I don't know how they'll react. However, personally, I'm all for being open, and in the past I have found that saying why X and Y upset me in a calm manner tends to work. In such situations, you avoid attributing blame or labelling...e.g., you would not say "You're an A**hole" but you might say "when you did X...it made me feel really sad and unappreciated..." or something like that. What are your thoughts about doing something like this with the person who upset you?
