Individual limits must be respected. If your family trespasses, that's a bad sign. Always respect personal boundaries.
Abuse in the family is never acceptable. No one, including family members, can physically or emotionally harm you.
You may feel unfulfilled and that things are one-sided. This could mean a family member puts himself/herself first and doesn't care about your requirements.
Asking about a person's life can be a show of interest, but if even a basic "How are you?" is absent, this is a warning sign.
This is a common occurrence. Even if it isn't done on purpose, hurting a youngster emotionally is a serious matter. Adulthood may be the time when you finally come to terms with this.
Ignoring your needs as a youngster can affect your adult life. If you've been through this, you may need healing.
If you never hear from your family, it could mean that you and your loved ones aren't close enough, or it could mean that they don't care about you at all.
Life experiences are better with loved ones nearby. If members of the family skip birthday celebrations, graduations, etc., that's your cue.
It's not worth your time or affection if someone is constantly berating you for anything you do, no matter how good you are.
In the end, you're human, with hopes and aspirations that come and go like everyone else. There is nothing worse than having family members that aren't on your side.
