She's in an even more vulnerable position then @Itsalongtime . Perfect brother isn't willing to "put a ring on it" then.
I get you. I'm 20 years older than you are, and I'm having therapy, not for the first time. Like you, everything in life seems to have been a struggle. The only thing in life that ever came easily to me was education. Complex childhood, huge negative work experience many years ago that has blighted my life/career, fertility issues, miscarriages, difficult marriage, loss of close family members, sibling outfalls, being let down massively by what I'd always considered close family. shitty ILs, yada yada yada, you name it, all on top of each other. You wouldn't know any of that looking in from the outside. Lovely family in the end but not always easy either.
I'm almost embarrassed telling the counsellor something else that's set off!! She keeps using words like resilience, integrity, warrior etc but I don't feel any of them, except that I have always fought tool and nail to retain my integrity - but as I said to them, integrity doesn't pay the bills.
I think my parents were proud but they were always ones to criticise the negative rather than celebrate the positive.
What I will say is, don't be me in another two decades with so many regrets. You have years ahead of you. If you need professional help with your little girl, look for that. (Your partner's father is an utter shit for saying that to you!!) Life isn't easy with a small baby either. I think you just get to the point where you feel so exhausted that you just feel that there's nothing left in the tank. That you have finally used up all that resilience and that you just want someone to carry the load. Plus you do get to certain points in your life where you do take stock of all that's gone before.
I think it's important to always have something lovely to look forward to. Be kind to yourself. You've had tough times (and I honestly believe that everyone gets their turn; even Queen Elizabeth had an "annus horribilus". No-one gets out of this life thing unscathed. I think you need to find a way to recognise the good in your life and let go the bad - and trust me, I know it isn't easy xx
