I’ve noticed something, everybody have something that can affect how they feel and how they behave. Some of them tell the others “just so you know that’s why I can be sad sometimes ” but the other part don’t say anything, they suffer but they don’t want to make anyone worried, that is sad because some of them really need someone to talk to.
I’m happy I have my mom to talk to because without that and without my friends I don’t know where I would have been, I remember the anxiety attacks when I called my mom crying and told her that I couldn’t handle this anymore (with this I mean the mix of stress, things that have haunted my brain for years, something negative that happened that day). But she was so calm and answered “yes you can handle this” and then I stopped crying and got my motivation back.
Some people don’t have anyone to talk to because the problem maybe is about their family. Just let them know how much they mean for you and that you will stay and be there for them. Maybe they don’t tell you directly but they will if they trust you.
