JustAnswer is a good place to get answers to specific questions, get guidance on treatment options, second opinions on case information and recommendations on resources. It probably isn't the best place to be seeking ongoing support as this is something that is usually better provided by a person/service that can offer more intensive services. There are a couple of organizations that aim to support carers/family members of people suffering from mental health difficulties and I would suggest that contacting either of the following would be your best option:
You can contact the National Alliance on Mental Health here. NAMI are a consumer organization that has a network of local branches that can provide a wealth of information on the kind of services offered locally.
You can contact Mental Health America here. The MHA website contains lots of information regarding mental health issues, treatment options and available resources.
If at any time you want an answer or comment on a specific matter then JustAnswer is the place go. In the meantime I would also suggest that you take a look at this excellent Cognitive Behavioral Therapy (CBT) based self-help program for Bipolar Illness
It will provide you with an excellent starting point for beginning to develop strategies for you and your son to better manage his illness in the future.
I hope this has been of some help. Please let me know if you have further questions or would like me to clarify any part of my answer.
