Divorced, alone and thriving at 50 and older?

I am looking for other divorced people over 50 (I just turned 60). The loneliness factor is my main concern after a 31 year relationship. I have great friends, a great therapist, great financial guy and after two lawyers, found a great lawyer. After working with my husband's business for 28 years plus other small jobs and lots of volunteering (at kid's school), I would like to find a fulfilling part time job and am starting by volunteering. I lack the computer skills for a business job, so after taking a mental health curriculum certificate course, I'm searching in the social services area, but there is no money out there. I don't have to work, but I HAVE to work for my own well being and passion to help others. I have two grown children 26 & 29 who live far away, no family close by, except my x's who still care about me, but who I can longer see at holidays, so I'm alone at holidays now, except for a "visit" from my kids. I only have one sister also far away with a busy life. Thus, I would like to join a group for company, ideas for things to do at this age as a woman alone after so many years a part of a large loving family system. I wonder if there are other men or women out there in this situation? I'm ready to see if there is a new life I can make for myself and would love to hear how others in this age bracket are thriving living alone again after so many years with a companion and intact family.   djsell
