Fear of change or rather the fear of not changing

Wondering around Bristol over the last day or so, talking to my friends and family, has made me realise a few things. If I was to sum up my state of mind at present I would say I'm scared. Scared of what happens next in my life. Before I thought this was a fear of change, part of me resisting and wanting to revert back to the old me. But the more I think about it, the more I think that the fear is that of not changing. I know what I am like, I know there may be a natural slide back to the old ways. I just have to resist.
