Grief and Grieving-Symptoms
Perhaps this will help you understand how a loss of someone who you were close with can present complicated emotions that if not addressed properly, can get worse over time.
If you are seeing a therapist, and the therapist doesn't listen, help you feel safe so you can discuss your emotions then the therapist is not doing his or her job. You "can" copy this link and bring it with you when you see your therapist. While it "is" frustrating when a therapist "fails" to be a good therapist, there is always room for them to be "enlightened" so they don't "fail" someone else who may suffer.
