Welcome, Phyxius!
I've had PCS for one year now and, like you, I've become frustrated at the lack of understanding in my family. What helps me to deal with that is to know that they really do mean well; they just don't know how to be supportive. For example, I often hear things like "just be grateful for what you do have" (which I am) or "you can't dwell on it" or "just hang in there," etc.
They fail to realize that I'm looking for their understanding and NOT their simplistic answers or advice. The more I can talk about my feelings with people who are supportive and empathetic, the more I can let go of those feelings of anger, frustration, or resentment.
Do you have anyone in your life who can understand and give you support? If not, I encourage you to find support through groups like this one.
I pray that you soon find new hope and a new direction for your life.
Don
