Closer to 50

A few weeks ago was my 45th birthday. Now I'm closer to 50 than 40. I don't get it as when I think of myself, I am either 13 or maybe at a push 20. I'm never 30, 35, 40 and definitely not 45.
I'm trying not to have a mid life crisis (yes, I assume I shall live to 90). I definitely thought I would be "sorted" by now, happy with myself. But it's hard with all the changes in the last five years....I have got married, had a kid, moved 5 times and given up my career and become someone who's life is devoted to others. Before this I earned loads, was respected at work, was able to go out when I wanted, see films, eat out, sleep late, meet mates, get drunk/hungover, buy anything I wanted (luckily didn't have really expensive tastes), have liaisons, have adult uninterrupted conversations. But at the end of the day I was lonely. I don't make friends easily - sometimes so shy but coming across as aloof. I worry that I have nothing interesting to say. It was easy to make friends at work as you had the shared domain.
Now I have two amazing people in my life that I love. And I'm much more creative now through the fogey old fashioned arts of knit, crochet and craft. I don't care. I love it. I do craft even when tot is not here. I love messing about with playdoh, paint, glue and most of all yarn. I meet some people through this and like talking to other crafters online.
In Plumstead, through playgroups and the nursery I met some lovely people. It's been a bit harder here. I have not made any friends in Scotland. In August tot goes to primary school - I'm really anxious about not being with my daughter so am going to look for some work.  I spoke to a mate the other day. She used to be a Chemical Engineer but since having kids her life changed. She is now a mum but also a bereavement counsellor and working in the NHS on cancer screening programmes. She gave me some advice about finding work...to volunteer at the school, to look for opportunities. She also told me to make friends with other mums on the playground.
I will do that. Cos I'm 45 and I'm sorted. Err....
