a little over 2 years ago, my boyfriend lost his 27 year old son to colon cancer after a very short 10 month battle. i noticed the normal signs of the grieving process, but these last few months have been very different. i see very definite signs of depression, but i am also seeing physical symptoms. can depression manifest physical symptoms of treatable ailments such as frequent colds, or sinusiits? he has never been one to be "whiny" when he's sick, or just lay around and do nothing, but lately this is exactly what he does!! NOTHING! poor appetite, poor sleep habits, etc. and all i have been able to do is let him "ail" and treat the symptoms of these "illnesses".
