All of us is on a different road on this journey, like you I struggled and I was worried why did others manage so well and not me, but I came to realise that its just how it is.
The lack of sleep and all the others things will dim into your past soon enough I promise.
I realsied very recently that I feel so much better, that the tiredness is not so often and it sort of happened without me knowing it. Its a struggle there is o doubt but over time I have changed the way I look at things, I have also made changes in my life and can say with complete honesty I have never been happier.
So my lovely, hang in there it will soon be over.
