My best friends are kind of sad and I think one of them is depressed. A lot of it has to do with the coronavirus and how our lives have changed. I don't know what to do. I want to help and have promised them that I will. I thought about doing a therapy group where all of us would open-up and talk. But I don't know how, or what to do if they start crying or feeling worse, or if the advice we give each other is ok. By the way we are 15 years old.
