I think it’s a reaction to pain meds (had surgery last week) or I’m tired or low blood pressure but am having the terrifying feeling that nothing around me is real . As If I’m watching it all on TV . Feels like before you faint . It’s horrible, and no matter what I’m doing I can’t shake it off - can’t get rid of it . I don’t think it’s a GP matter but what can I do? Don’t know what to do and don’t want to feel like this .
