Is this common in anxiety?

Lately I have been feeling detached like I’m watching myself through a screen and feel like I’m no longer in my body. It’s a very weird scary experience for me as I feel like I’m also dreaming as well. I’ve been depressed and stressed out from work, barely anybody to talk to as much since my friends and family either are working or have something else planned. Heart palpitations, shortness of breath, and fatigue. My sleeping schedule is messed up, how can I help myself overcome anxiety? I would like some helpful advice on what can help me out a lot. I hate going through this feeling a lot.
