Hello confusedangry, I want to welcome you to the forum. This is a friendly place with supportive and kind people.
I can understand how you feel confused when you see yourself as strong and now
you feel down. Feeling down is not a sign of not being strong.
I wonder has something happened recently in your personal or work or in you social and family life? I realise you have said there was no reason and no money and health issues, but I am thinking could be anything positive or not positive, could be something small . Of course there may be no reason at all.
Have you spoken to anyone, friends or family or your local GP about how you are feeling?
How is the way you feeling affecting your life at home at work. ?
Well done for reaching out and sharing your story.
know many people will have felt like you are now. You are not alone.
There is support here.
If you want to discuss things further, feel free to post if you want to.
