Thinking about getting a cleaning job

Thinking about getting a cleaning job I block, a lot. It makes my current job challenging and anxiety-producing. I'm worried about my mental health. I have been considering becoming a janitor or work for a house cleaning company so there would be miminal situations where I would have to speak for long periods of time or answer a phone. I know avoidance is bad but I don't know what to do. I just want to be comfortable in my own skin, and everyday feels like a moutain to climb.
