I feel so ashamed and stupid
That's the internalised Parent voice (unconscious) talking; don't give it power by agreeing with it from your conscious mind.
Oppose the negative unconscious Parent voice by developing a positive conscious grown-up voice - get into the habit of telling your inner Child that:
- you love her
- she is a loving caring person
- she is better than her actual parents because she doesn't go around hurting people for no good reason, so she doesn't have to listen to their poisonous messages any more.
Imagine you as a grown-up taking yourself as a tiny baby in your arms and telling her that:
- the nightmare is over
- you are going to be there for her
- you are not going to let anyone hurt her
- you are only just starting to learn how to care for her so you might make mistakes to begin with - if you get it wrong for her, tell her that that matters to you and that you will want to put that right for her
- you understand that she is going to find it difficult to trust you to begin with and that that's OK.
This stuff will be difficult. There will be a lot of opposition from the Parent voices. Don't let those Toxic Twats win!
Let me know how you get on.
Love and hugs to your inner Child.
I just want to ... be as happy on the inside as I appear to be on the outside.
Who gets entertained by the show you put on?
