I'm sorry you are feeling this way
You definately don't deserve it. It sounds like you are having a tough time of it. Just be honest with your Therapist and talk it out. I'll tell you a little about my experiences with DR and DP. It sounds like you might be getting obsessive about these feelings you are having. Depression and Anxiety make this worse. I think you will find that a lot of us have the same or similar symptoms. The thing you mentioned about your feelings and emotions towards your family sounds familiar to me.
When I go a long time with DR and DP I start to feel like I'm disappearing. I have difficulty actually feeling anything as if my emotions are being sucked away. I often feel like I am being swallowed up by a deep hole and I see things happening from far away or like there is this sheet that is separating me from the world and the people who love me. I also feel like my love for my family has been muffled or hijacked. My head feels numb as well as my body and my senses of taste, touch, smell and vision is very messed up. It feels like I'm touching a dead body when I touch my arms and face. I feel like I am smothering when I eat and my sense of smell is just gone. My hands when I look at them doesn't look like my hands like they don't belong to me and I worry about what has happened to my body. I remember worrying as a teenager that I was already dead and I was in Hell. I still have thoughts like that sometimes. Its important to know that you are not alone in this. I hope you have family or friends that are supportive.
Blessings to you. I hope you feel better soon.
