ocd

I have a 14 year old. He has a couple of issues. he stutters. Lately, we were noticing some actions he performed routinely. For eg. hand washing, toucing feet, cracking knuckles, changing clothes very frequently. He adds on a new habit every few days. On speaking to his speech therapist, he suggested my son might have OCD. We have not visited the therapist for that because we do not want to give him anti-depressants and other conventional medicines. I ama beleiver in alternative medicine. I am currently giving him inositol. But I need some direction. I feel like am shooting in the dark. He is a tall and heavy kid prone to acne and oily skin. Tends to overeat and has constant issues with weight. he is not slef motivated to do a lot. Tends to be fatigued most of the day. Please help!
