Where do I find Non-ADHD Spouse Support groups?

I'm the Non-ADHD spouse. My Husband (33 years old) of 2 1/2 years was recently diagnosed with ADHD. We have been together for a total of 4 years, but it feels like a lot longer. My health hasn't been good. I have been experiencing migraines on a daily basis (due to being stressed), I have severe depression, I regularly think about suicide, and I have really bad anxiety attacks quite frequently. I really don't want to go on medication since I don't want to deal with any negative side-effects. My Husband started taking 2 daily doses of Adderall (10 mg each) about 3 weeks ago. While I have seen some improvement in him, it hasn't been enough to positively influence our relationship. We were seeing a counselor together (who specializes in ADHD and has ADHD herself), but that only made my anxiety and depression worse since I felt like she was blaming me for all of our problems. I am seriously thinking of leaving my Husband (at least temporarily) so I can take care of myself. I'm just afraid that I'll end up totally alone. My biggest problem is I don't have any close friends or any support at all. I have isolated myself from everyone so much and I never socialize anymore. I don't feel important or like I matter at all to anyone.

My Husband has been going to a monthly ADHD support group, but I can't seem to find any support groups for non-ADHD spouses. We live in the Pittsburgh, PA area. Does anyone know where I can find some support?
