I posted a longer variant of this to friends on Facebook, but please remember a saying that social media merely shows people's "highlight reels", not their day-to-day life.
More than ever, people are struggling. Please do not attribute any weakness or negative quality to yourself if you are struggling yourself - you are among millions.
And do not feel there's necessarily any strength in "keeping it to yourself." Many people are letting that build to unsustainable levels inside themselves. Be honest with a friend that you are struggling. If, for the moment, you are without friends, you will find that there are anonymous people who do care about you on Discords, chat rooms.
Or on the end of a hotline. You don't necessarily have to have active plans of suicide to call a suicide hotline. A lot of the time, some people who kill themselves have deep apathy about life right up until a moment.
I'll be honest that I am one of those struggling. I am not actively suicidal - I may possibly have some passive suicidal ideation (certainly the apathy and some lack of emotion) - but I am fortunate enough to have a good therapist. It is merely that I've lost a lot of people and gone through a tremendous amount of difficult change in the last year.
My maxim in life has been this: at the worst of times, just take the next step forward. That's all you have to worry about, that one next step. They build up.
Good luck to everyone here in 2023 with those challenges you find yourself facing. Don't feel as if you are excluded from the human race by your struggles. You are facing variants of what we are all facing.
