Depression Support Group
Depression is a real and debilitating condition that is often misunderstood by family and friends. Its meaning can range from a prolonged period of sadness to an actual mental illness with specific symptoms. Find and share experiences with others who are going through the same struggles.
Only a doctor can make a diagnosis as to what is going on with the lil guy but it sounds to me like he is developing a personality issue or a bi polar problem. You are right, normal depression usually do not involve them wild mood swings.
I also have to add something. The situation with step dad has to stop if there is any chance at all for the lil guy to have a normal life. If it takes police involvement, so be it. If he is abusing the lil guy, all the medicines and doctors will not be able to help while he is being abused.
Now saying that be sure he goes to the doctor and make sure that the doctor is told about his being suicidal. I can tell you my son did the same thing at the age of 8 and we changed doctors so many times it was not funny till I found one who would listen to what was going on and get us the help we needed.
the boy's behavior is poor because his parents screwed him up. the whole family needs work.
Only point out the good things he does...dont focus on the bad. Let me know how this works.
