H. I am so sorry for the loss of your mother.
You are going through every emotion all at once. Heartbreak, sorrow, Loss, betrayal, as well as Love, comfort, and joy.
This would be a lot for any one.
When we are children we are so trusting. We believe that the people in our lives are always telling us the truth.
As we mature we realize that everyone has their version. Your father had his, your mother had hers and you have your own. Put that all together and stir and somewhere in there is the truth.
You were a child. You were dependent on your father. When you begin to realize that he told you one lie, you begin to question everything he ever said.
This happens to most of us. But most of us do not have such a big lie told to us by our beloved parents.
This is a time for you to embrace this family that loves you and is so grateful to have you back in their lives. I suggest you find a therapist to work through all of your feelings and your fears. This person will mainly listen to your history and then ask you the questions that only you can answer. This person could also clarify what your worries are with you, so YOU can decide how to handle them.
It will take a lot of this fear, and confusion from you.
It will also probably give you the strength to be able to ask (demand) the truth from your beloved father. I know that is what is really worrying you.
Our parents are not perfect. They are human and all have their own faults. Until we can admit and accept this fact, we give them way too much control in our adult lives.
I am sending you strength. You deserve to know your truth and you should never have to fear the love people have for you.
