it shows on my face

went for my facial todae...according to kelly..my face is not in a good shape...asked me if i have been very stressed..told her i dun think so coz sch is very slack just that maybe there are things that i am not happy abt...after discussing, we think the problem lies with the working shifts...because i have different working shifts everyday my health and my skin is affected...which is kind of true coz i know my health is very lousy when it comes to this...last time in my old sch, even when i covered my colleague's shift for a short period of them, my health will already be affected...let alone for now my shifts are permanently changing....kelly just said this,"ai yo quit lah...this job no good for ur skin"...haaa.....
