Many of the support groups on this list offer free services or request an optional donation — so there isn't any pressure to pay beyond what you can afford. However, talking with a professional therapist or coach usually comes at a higher cost.
It isn't common for insurances to cover support groups, and these groups don't advertise that they're approved for insurance coverage either. However, it's always a good idea to call your insurance provider to double-check if any of these services or expenses are covered.
