Welcome to PC and please read a lot and post a lot. I can tell you it does really help. At least we know we are not alone in what we go through.

Sounds like a classic case of depression to me. I know something about feeling like a burden. I moved away when I was 19 and worked my whole life, BUT in recent years my depression got so severe I couldn't hold down a job anymore. I am 50 and sitting here at my parents totally relying on them financially. I do not like it one bit. I am an emotional and financial burden to them. I decided that I would not longer be an emotional burden by not sharing with them my everyday ups and downs and what is going on in my head. I do have other sources of support that I use however.

It is much harder when you are out of school or work as when you wake up you don't feel like there is anything worth getting out of bed for. And then for me even when I do have a very large reason to get out of bed I can't force myself to get up and serve that purpose. So a sense of purpose does not always fix it.

Have you thought about telling your parents that you think you suffer from depression and may need professional help?

Have you thought about telling your friends what you are going through? They might surprise you.
