I know how you feel - my son has gone through all sorts of therapies as well as evaluations. He's going to be 5 in a couple of weeks and I will say that in the past two evaluations the pediatric behavioralist and her team (OT, speech therapist, psychologist) believe had they seen him for the first time in the past year he'd not have been diagnosed on the spectrum - so, the therapies are doing him such good. It's hard to see the positives many times as it's very hard......but then I get a hug, or my son tells me he loves me, or I hear how smart he is, etc. etc, etc. I was getting stuck in the negative so much that when I went back and read former evaluations (he's had a couple a year since he was just under 2) and I see what he can do now = he's not even the same child!!!!!!! I've learned to realize my son has made me grow as a person and appreciate everyone for who they are.
I couldn't find a local support group but I poured myself into books written by parents and children who lived the same situations I was going through - I also joined some online groups for the specific 'issues' related to my son. dailystrength.org has a lot of supportive parents and family members.....
A few years ago I was so overwhelmed and worried about who my son 'would be' or 'wouldn't be' and I never would have believed I'd say this but = things do get better.
