Singleton1311 I know the standard answer is "join more clubs" but in most cases this doesn't work. You can be dreadfully lonely when surrounded by people.
I've found that emotions like this run in cycles and I wonder if this is the same for you? Pre-menopause, I had few problems with emotions but during and after and still now, in my 70's, I find there's a pattern.
There will be days when I feel so weepy and low and prey to negative thoughts, without any specific reason for it.
Then, in a few days, the grey clouds will lift and I can pull myself out of it.
Lockdown doesn't help of course, it's an unnatural situation and health professionals are seeing a huge upswing in emotional problems along with the physical ones, so you're by no means alone.
I suspect this is what's called 'situational depression' (yes, there are many kinds of depression, not all clinical/suicidal etc) and once we all get back to normal, will gradually fade.
The very fact that we are forced into an abnormal situation of exile, is enough to make anyone lonely.
I'm going to send you a Personal Message - do you know how to access them?
