Him not being broken depends on whether he chooses to feel himself to be broken or not.
You can only do the 'you' bit of this, and recognising that is part of it. It is huge, yes. Counselling got me to the place where I was ready to take it on board, but when the penny dropped, it happened in an instant. It was like a piano dropped off a roof and hit me! Mindset changed, instantly: I'm not unhappy because I'm broken, I'm unhappy because I choose to be around people/in places that don't make me happy.
It's SO simple, and it's all based around the fact that you don't need to change anything about yourself. You're fab. If people don't appreciate that, they can bugger off.
One of my big realisations was 'The only thing I need to change about myself is my partner.' It was almost funny in its horribleness. But I had plenty of people in my life with whom I felt sane, loved, appreciated, respected etc. It was only with my partner that I felt like I was somehow faulty.
Sorry, I'm off on one again.
Yes, I recommend counselling 100% BUT I got very lucky and the first counsellor I went to was the right counsellor for me. It's like any relationship; you have to choose well, so if you have a session, and you come out feeling like the person didn't 'get' you, or wasn't listening, find someone else. I wish you luck with this. For me, it was like learning to parent myself, in a way that I hadn't even been parented as a kid. Now I'm like the parent of my own feelings, so, if my feeling is sad, I give myself a metaphorical hug, tell me I love me, buy me a bar of chocolate, and treat myself to a shit film lying in the sofa under a blanket. Previously it would have been an internal 'For god's sake, you prat, why can't you just be happy??'
I will say one other thing, whilst I'm wittering :) It was helpful, with regard to 'being broken because of my past', to recognise the difference between fault and responsibility. It was my parent's fault I turned out feeling like I was broken, not mine. YAY!! Finally free of blaming myself for all the rubbish about me! Fault looks BACKWARDS. It was (and is) my responsibility to not drag that brokenness into every day, every relationship, every decision I made. YAY! Finally I'm allowed to do whatever the fuck I want and nobody can tell me I'm wrong!! Responsibility looks FORWARDS.
You are yours. You belong to you. You have to take care of you, treat you as you would a vulnerable child, because that's what we all are, emotionally: confused little kids in a big world with no set of rules to follow. As adults, we develop the cognitive function and experience to support our little confused inner kids. So many of us spend our days telling the little one inside to just shut up. It's a happy life when you mollycoddle that kid instead.
