Nausea and giddy

Hi all, I’m currently 8 weeks + and feeling very unwell. A combination of feeling nauseous (but didn’t puke), giddiness, lack of strength to even walk about the house. Anybody feels the same and at which week did you start feeling better? Any tips to improve my situation? As I’m lying on the bed most of the time so I’m feeling kinda depressed. Thanks a lot.
