About 2 weeks of feeling down and fatigued. The first 3-4 days just rough but the last bit just weak. I think I felt myself about the 3rd week. Hang in there.
I don't know the situation you are in but if you aren't paying rent then cleaning the house is not a bad tradeoff. I know when I was a teenager living at home I was asked to clean the house but my parents provided me with a home, food and they were trying hard to work constantly that keeping the house clean really was just my part in helping.
