Dear Liz: My son, who is almost 50, is mentally and emotionally challenged. He has been unemployed and homeless for years. Although not a criminal, he’s been in jail a few times because of his explosive, combative nature. There seems to be no help for him in the state where he lives. I do send a few dollars for his basic needs when I can, but must be careful with my budget. Do you have any tips that might be helpful in this situation?

Answer: You’re living with a heartbreaking situation. You want to help, but given your age and financial circumstances your ability to do so is limited. Unless you set some boundaries, you could run through your savings and possibly wind up homeless yourself.

You’ll find some helpful resources at the National Alliance on Mental Illness (www.nami.org), which offers information and, in many locations, support groups for families. Another place to find comfort, insights and suggestions would be a 12-step group for co-dependency, such as Co-Dependents Anonymous (www.coda.org), Al-Anon (www.al-anon.org) and Nar-Anon (www.nar-anon.org). Substance abuse often accompanies mental illness, so you may find it helpful to talk to others who have dealt with problem drinkers (Al-Anon) or addicts (Nar-Anon).

Every state has at least some resources for the mentally ill. You can start your search at MentalHealth.gov to see what might be available where your son lives and let him know the options. But as the members of any support group will tell you, you cannot fix another human being or force him to change. What you can do is to take care of yourself.
