The problem is that a lot of people don't know "how" to care so they distance from someone who is struggling or try to change the subject. That doesn't mean you don't deserve to have someone in your life that does care. A lot of people gravitate to positive people because they hope to discover some ways in how to attain a more positive outlook and way of living their lives and a lot of people literally plow through life and never really sit and engage the way you need to be engaged and heard.
The best place to go when needing help is to find a good therapist that understand how to help a patient work through trauma. It doesn't matter how severe a trauma is, what matters more is that you get help to mourn whatever you need to mourn and learn ways to help yourself evolve into a stronger individual despite the past. Each person is different in how long they need the guidance of a good therapist.
