Where can I find the support system for my mental illness?

Several. In addition to my colleagues' responses, you can also check mental health america -- http://www.Nmha.Org/ -- and national alliance on mental illness -- http://www.Nami.Org/ there may be local affiliates of these organizations where you are, with helpful resources for you. Mental health centers do exist in some states. Some churches & religious communities also offer support.
Try googling. Try googling your illness in local level to find help.
Support system. Family, friends, your local mental health center would know resources to refer u for individual and group counseling. Good luck.
