Sharing Our Innermost Thoughts

I usually get this feeling, like something heavy on my chest and it just wants to make me cry, my legs paralyzed, my hands frozen. With a heavy heart even when there’s nothing going on.
I get this rush of negative thoughts, overthinking which makes me paralyzed every time by thinking about the worst outcomes. I really really want to get out of this. I don’t want to feel this, I don’t want to overthink.
How do I deal with this?
Can someone please guide me?
I feel like an emotional mental tornado of negative emotions and thoughts going inside of me. I want to break this loop. I’ve had enough. It would be of great help if any one of you knows how to deal with this and get out of this.
