Because of the c-PTSD your mind is more attuned than most to searching for answers to problems – with the trauma the answers may not exist; with the age related issues the problems do not yet exist.
I dread living alone.
I'm dreading older age.
When you fear or dread something your mind will try to think of every conceivable way of avoiding that thing happening; when children are scared of the dark they will refuse to go to bed or be left alone.
If, however, you can reframe your thinking – with professional help – you can change the way you think about your future. Curiosity is probably the best substitute emotion, because when we are curious about something we explore it from every angle, rather that push it away.
You will get older. But you might do as a champion bodybuilder or as someone who travels the world investigating rare moths. Or as a public speaker on the benefits of ageing.
You might live alone. You might be delighted to do so. Or you might start a commune for people who were once scared but are now curious.
Your worries are not baseless but they can be turned around. I'm reminded of what @FixMePlease wrote on my AMA;
"Hello thread. I posted elsewhere on MN a few weeks ago, feeling low, lost and, quite frankly, broken. This was the name change I used to create that one, desperate cry for help. I was feeling overweight, middle-aged and menopausal. @eyesopenwideawake was on of the people who responded and offered support. Long story short, she took me on as a client. I've been on MN forever but this is the first time I've ever disclosed my real name to another poster, let alone met up with them online. It just felt right, and I'm glad I went with my gut on this.
I genuinely recommend getting in touch with *@eyesopenwideawake (and have recommended her to quite a few people IRL too). Our work has been truly transformative for me. For the first time in years I feel like me again and I've found my drive and direction. I'm focused on my health and career goals and can't believe the difference just a few short sessions has made. It feels like magic."
