There are lots of personal things I don't feel comfortable sharing with 1) my parents but my boyfriend is fine 2) not even my boyfriend 3) only Psych Central (I like the community here)

My point is that all of us feel comfortable discussing different things with different people in different degrees and there is nothing wrong with this. As long as you have some sort of outlet for all that's on your mind that's all that is really needed.

But of course if you feel like you want to get closer to your family and discuss deeper issues, it is a good idea to open up to them. You can even write a letter and give it to them to read. That may be easier than verbally starting a deep conversation out of the blue.
