Well, I am also suffering from depression. Don't get me wrong here. I am not whining or giving some excuses. It's been like 1 1/2 month since I last went to gym. My diet is crappy before my diet was okay. I just want to know one thing. Whenever I am depressed after few mins of my depression like 45 mins to 1 hrs I start feeling dizzy & drowsy also, Why is that? Any help will be appreciated.
