Is it normal i sleep all day and stay up all night to avoid people?

I don't particularly like it but I'm up from around 10PM-7AM because I know I won't be bothered during that time. During the day I awake occasionally and I might do something for an hour or two or just use the bathroom or eat something then I go back to bed because I don't want anyone bothering me. If I'm up and I hear someone out in the living room doing stuff I immediately force myself to sleep because if they knock on my door I'd have to get it.

Most of the time it's because I want to be left alone. I don't want to talk to anyone or be around anyone. Other times I get really anxious/panicky if I think someone might knock on my door or catch me outside my room. I feel bad at times but I act this way with practically everybody. I won't call my parents for months or reply back to a message in weeks because it causes me a lot of stress. I guess that's really what it's about. A few months ago there was a time when anything having to do with life (answering a phone call, paying a bill online, walking the dog, checking the mail, cooking, working, getting out of bed etc) would make me cry because it was so stressful.
