Random attacks/breathing issues

[Renee111]

Hi guys..

I was hoping maybe someone has experienced what I'm going through right now.

I had some dinner then I laid down, I stood up and my heart started beating so hard/palpitating, so I drank some water and sat down now I'm feeling a little breathless and feel an attack on the brim.

Has anyone else experienced shallow breathing/feeling like you need to take a deap breath...
