Hyperventilating and palpitations.

Hello doctor, I am having palpitations mostly when I sleep at night, which makes me unable to have a sound sleep. Palpitations are more when I stand or light activity. My resting heart rate is 75-80. At night, it's 95-100. And when I stand or go to the bathroom, it increases to 125-135. Also, I am hyperventilating (taking a deep breath) often, all day. This hyperventilation is more prevalent when I slightly move or take turns. Even when I sleep at night, the moment I wake up, I take a very deep breath, every time. Also, often, I have the urge to yawn. For all these reasons, I am having continuous conscious or manual breathing, like am concentrating on my breathing all day. This is happening from the last 10-12 days. I go for walk in the morning, without any breathing difficulty. (Spo2 95-99) at rest or after walk/activity. Bp is in the normal range (120/85). It's making my quality of life very poor. Is it anxiety? Or anything else? Please help. Do I need medications or any treatment?
