Yet another aspect

I have posted on the other current thread and now another "problem" has reared it's head.
I have realised that I haven't been out on my own since my H died and now I find I can't do it.
Is this normal?
Will I find the courage?
Each time, not many, I have had a reason and someone else has been involved.
I got up this morning thinking I would do some shopping.
I just can't do it.
I don't drive so would have to walk to the bus, I might meet neighbours who perhaps don't know, I would certainly meet someone on the bus which is a community bus ,running just a few times a day and used by locals.
I am surprised by this, I am outgoing and friendly, I am quite scared by the realisation.
