I agree with those who say, do what you feel comfortable with. BUT do realise that the virus will not just go away, and will probably be around for a long time. Worst time will probably be early in New year.
I have been very pragmatic. I live by myself, am going on for 80yrs old. However, I also knew that I had to care for my mental as well as my physical health throughout. So, I met up with my local daughter in local park most days during April and May ( usually well apart, but at least someone to talk to). I continued to do my weekly supermarket shop myself. Did go to visit another daughter and g.daughter and stayed overnight a few weeks back. I go to local shops now, but always when they are not too busy. We have had family outings - but always, and only, to outdoor places. Local daughtert and her family now count as my bubble family - so g.children do come to visit me in my flat now.
I have not yet ventured into a restaurant, or had my hair down, although plan to do the latter in about another fortnight.
So, I have not kept myself totally isolated, which has been very good for me. I do not take notice of what other people do or do not do. I go with my own risk assessments and do what feels right by me.
This is what you need to do. I was quite astonished at someone I know, who has been totally and completely shielding since March. First time yesterday she met up with her son and g.children, first time she went out for months, and they went to an indoor restaurant!!!! But, each person must do what they feel happy about.
So, no-one can advice you, nor should you be upset or take notice of what other people may be doing.
Good Luck
