Vera, in case noone has said, welcome to TP and I hope you will find advice and support and help here.
I am glad you are willing to try your local carer's cafe. I am a by nature a shy person and definitely know that anxious feeling about going new places and meeting new people!
Here in the States, sadly, we don't have carer's cafes with coffee and cake. We do have support groups that are run by the American version of the Alzheimer's Society. I know I was very nervous about trying these out but they have been very helpful. I've gotten local contacts, good ideas, been able to attend lectures and workshops that are very informative, and so forth. But most importantly, it can be amazingly helpful to be in a room full of people, who really understand what you're experiencing and who are very supportive and kind. And I'm sure if you just want to listen, that there will be no pressure to participate.
Best wishes to you.
