Help me turn my life around

Anyway, I'm a 48 yr old woman, married, working full time and trying to complete my MBA. My married life is not doing so great, my job is extremely demanding and my studies are not really progressing right now. I need to take control of my life and make some significant changes.

I am a CEO of a medium size Aboriginal Community in the remote outback Western Australia. Due to my location, I feel quite lonely and meeting people is virtually impossible. I need support to make the changes I need to get my life on track. I need friends who are trying to make changes in their lives. I need to lose weight, gain confidence, make time for myself, improve my appearance, stop stressing, and then naturally get my marriage/studies back on track.

I know it sounds like I'm too needy, but I am a good listener, good friend to others and will give back just as much to those who give me their time.
