I’m just venting feel free to chime in

Hi I think I developed anxiety stemming from the passing of my mom. I have recently got better over time but it still comes and goes. I am afraid of feeling my heart rate beating fast, afraid of anticipating things and the anxiety of speaking but I have had it most my life. I would absolutely hate classroom presentations with a passion. I use to get palpitations a little shortly after waking up with it not happening after a good while it happened again for the most part I got up and pee like usual and I start deep breathing did any of you have similar thing like this happen to you?
