freaking out! anyone have this happening??

Last night I woke up gasping for air and I was having the hardest time breathing. I was sweating too. So I sat up and my hands and feet were tingly and I felt pins and needles in my feet and they were getting swollen. So I propped my feet and tried to lay back a tiny bit but my breathing was crazy. So I sat there trying to control it all for a couple hours. So scary! And in the day my vision is messed up. Idk what it is! My heart was pounding super hard and fast too
