A Little Freaked

I just signed up and I am a little scared. I have been getting progressively more unhappy with my health and my relationships. I know what making a change starts with me, but I am very afraid. I am so tired of being afraid. I want this to work, I need this to work. I just don’t want to sabotage myself, something I think I do without even realizing it! I am not even sure what to start, trying not to get overhwhelmed, HELP!
