I think I have done all of these things in different situations! There have been points in my life when I felt so overwhelmed that I just couldn't process or deal with things. Then I learned that it's okay to break down every once in awhile. Becoming aware of things can be intense, especially for emotional people. Sometimes it can feel a bit hopeless. Still yet, I feel like it is so much better to learn what is going on in the world and in my own life, the good and the bad.
The more I try to learn the more I realize that I will continue to be the naive one in many circumstances because there are so many things to learn and knowledge itself is always changing and growing. But having an open mind and a lot of patience is all you ever really need to show you care. Growing pains hurt no matter how old you are but if you deal with them gracefully they will make you a better person in the end.
