Does BiPolar illness cause this change?
I have BiPolar and I know the signs, he has shown a few symtoms of being manic but not alot. His moods seem to be all over the shop from what you have described some of which are depressions. It might be Bipolar along with PTSD or perhaps schizophrenia. For those of us who suffer with mental illness we are excellent at wearing masks, its our only way of coping on a day to day basis becasue of the lack of understanding in society. For the ppl who answer with things like ‘run for the hills’ perhaps think again before you open your mouth and open a book instead. There is a excellent site called MDJunction its ppl helping ppl and has a huge variety of support groups available. Good luck.
