Calling for help

I have MANY problems, in my mind, in my heart, in my soul... Literally every part of me is cring for help, for comfort, for a place where I can be safe. But I've never had the courage to speak about my pain out loud. I've tried, I SWEAR I've tried, I've even imagined very detailed dialogues with some people where I explained perfecly everything but when I have the occasion to actually talk about that with those people, only my usual phrases come out: "I'm okay" "I'm fine" "I'm just tired". And the explanation of my problems? Not a single word. What do I do? I can't talk about this, but can't even continue suffering in silence, I'm exhausted, not only tired of this. Thanks for reading by the way
