What do you do when you get that heavy feeling in your chest...of feeling unsettled and almost a little panicked?

Anxiety or a panic attack. The best thing to do is acknowledge it and ride it out. The more you try to handle it the more often it will happen and it gets worse.
Its a horrible thing to go through but billions of people experience it all over the world. We just have to acknowledge our feelings, positive & negative and hope you don't do anything stupid before its over

It's anxiety. What do you worry about?

And, no, it's not just you. Lots of people get that same feeling.

I remember the times when it happened before.
When I know it, also why.
And that I´m here, still walking my path, the best as I can.

I only get that feeling when I'm about to fight

Perfectly normal paranoia.

talk about it then nap

Suck my asthma inhaler.
