am going to ask my mum to write to you I think on this front.
I'm from a very loving family, very secure etc had a very happy child hood. BUT mum started a college course, we (DB and I) both went off the rails a bit - won't bore you with the details. I had councilling he, needless to say we both really pushed our parents to the limit, big time.
any how at 16, with her support I had the councilling, we used to go for a coffee after to discuss things, I know for a fact I said some horrible hurtful stuff to her - but it was how I felt at the time. I moved away, but in fairness it wasn't until I had DS I fully appreciated how much she'd done for us and that it's not easy being a parent. she's only human after all, now i have so much respect for both of my folks, her mum especially, as she managed a full on degree plus two tear aways and the house running etc.
now she's the one I turn to, we have a fantastic relationship. it takes time and patience I think, as someone else said accpet what she's saying but to a degree she also needs to accept and take her share of the blame in all of this (if there is in deed any you feel is hers to take).
does she have children - it's no defence but it's true I honestly didn't appreciate how hard it was for my parents until I had my own house and now of course with DS.
