I had a really hard time talking to a counselor about the issues I had with my father although he had somewhat identified the problem.
He had me write a letter to him, one that would never be sent. I've managed to lose it but that may be no bad thing. Talking to him about how deeply unhappy I was about my relationship with my father and how it was affecting me ....and had been for as long as I can remember did help.
I would suggest writing some stuff down, maybe a list of things you feel you need to try and talk about, at least that way you just need to say you have written a few things down that have been troubling you and hand it over, can you email them ? I'm just suggesting what I might do knowing how hard I find it to genuinely open up to people, it may not be appropriate for you.
What I do know is that all the disappointment, resentment and the sadness and pain that comes from the little boy inside of me has damaged me more than anything else. You have to keep working on finding ways to deal with these things in a less harmful and more mindful way, I've by no means got this done yet but just recognising it was life changing.
What can I really do to make a little bit of this better........not become the very thing I despise so much, try and do the things he didn't do and try not to resent him as he did his father.
You started this thread so you can delete it anytime you want, shoot me a PM if you need me to do it.
all the best
