@ehBeth,
For teens (at least my teen) it is not us around her - I keep (and her older sister) telling her about what are the current benefits - this is preparing her for college as she will have to be self-motivated there in her studies; for example.
The problem she is having increasing her anxiety is that certain friends are the doom and gloom kind. - those saying this is going to last through next year- etc., etc.
I tell her no one really knows how long this will last - you could be going to back to school in 2 weeks or it could be longer. We do not know. I tell her when you start texting, group chatting, etc. and some of the kids get bleak - just to shut the phone off, cut them off - and do not talk with them. I make it clear that I do the same with the news - when you surround yourself with negative people you are going to feel that way.
I pointed to her - the performance training coach - he is so positive all the time and full of energy - that is why it is so important to work out with him and the group virtually - it is very positive not just the exercising.
He, quite honestly, is great. He not only works with their exercising, but nutrition, and being good people. It will be great when she can go to these classes in person as well.
