Discouraged

I am feeling so discouraged today. My son Rey has been cycling so bad with his moods and I just don't know what to do for him anymore. He goes from happiness to anger to sadness so fast it scares me. I found out this morning that he is spitting out his medicine again when no one is looking. Found the evidence in his trashcan when I cleaned his room. That explains the quick cycling.He says stuff a lot lately too like he wishes he were dead, he says he wishes a car would hit him etc. He is only 6 years old!!! Luckily we have an appointment next week with his Dr. I am hoping we can resolve this.He needs counseling but the problem is that there is such a long wait list everywhere. We have been waiting for almost a year.
We have an appointment today with the gastroentrologist. I am hoping he will do some testing because Rey is not gaining weight and is not eating much of anything.
