hi, am 28yr old. Last few months back due to depression i have smoked a lot and even when I was having a huge cold(flu) with lot of cough. Now, I am ok from the depression as well as from my flu since last 2months but somehow I am feeling very weak and energy less. I am also getting tired very easily with little physical activity. Also, sometimes when I take rest at my work places I suddnely goes into numbness of my limbs (like paralysed). and then I cant move them for next few minitues. sometimes even I feel that i go unconsious inbetween my daily life. Even my mind is not working as sharp as early it use to. Also there is a feeling sometimes that I am about to die soon as I really feel enegy less at some points in my daily life. I want to know is that some problem with my health or it is just I am overconsious as I am working very hard.
