What is this feeling?

I feel like I want to jump out of my own skin and I am full of tears. I know this could be multiple different things that’s why I’m just putting it in the rant section. I feel very overwhelmed and hopeless and like a failure in every area of my life. No one would understand so I don’t talk about it. I talk to my therapist about it sometimes. But literally I want to crawl out of my skin, it’s odd.
