When it all comes falling down

Well after our last meeting with Cade's teacher we started to work more with him and his attitude. He is on a contract right now and it doesnt appear to be working so well. Jeff and I are really concerned about him and the way we see him progressing. He seems to get distracted very easily, has a very hard time listening and staying seated, he also is a very emotional boy and lately he has gotten emotional over things that you would never think he would. His sister was acting like a cat and for some reason Cade did not like this so he started crying and moved to the corner of the couch just in tears. She was not even doing anything directly to him. That was not the only time that he reacted to something like that. Well we decided to go to the peditrician to see what he thought... A little back history on the last episode we had at school. Cade started making fun of a kid who is "special" along with his friends and this boy proceded to take a pencil and throw it at Cade's eye. Well no damage was done but we ended up sitting at his school all day to ensure that he did not misbehave again. So this led us to the peditrician. Well when we saw the ped he had us talk about Cade and what our concerns were. He did not ask us questions or tell us what he was looking for. Once we were done he stated that Cade has several symptoms of ADHD and possibly depression. I just sat there wondering why my genes had to pass onto my son. I have depression and have had it for a very longtime. The ped told us that since I had been diagnosed with depression when I was young that it increased my childs chance of having depression. Well I know what you all are thinking about the ADHD part. Seeing as that is one of the top diagnosis that ped's give kids that seem difficult but my ped is not like that. He told us that he doesnt like to just put a kid on meds and hope it is the problem but that he feels that we should have the test done to help diagnois it and to try every possible thing before deciding on meds. I agree with this 100% since I have been taking meds what feels like my whole life. We make our game plan and leave the office and in the car ride home I just think why did I have kids when I knew that my "craziness" which Jeff and I call it could be passed on to my children. Why would I want them to go through anything like what I have? Why would I want to see them so sad that they cant even function and then I turn and look at my beautiful angels just smiling at me and it just rips me apart to know that they could live a life with such sadness. I love my kids and I will do anything to help prevent this... Just have to find out how.
