Feeling a lack of support

I feel stuck and have been feeling that way for about 3 years now.  I came from an abusive background and I spent almost all my time dealing with and healing from the situation.  I am a 26 year old female and am only now deciding what I want to do with my life.  I see so many of my friends younger than me achieving so much and I am glad for them but I want some of that happiness myself.  I know their success is due to the most powerful law being LOVE.  The problem is I don’t have that loving support in my life that one needs to succeed.  How do I succeed in my pursuit of a career when I have no love in my life?  The only person I feel I can rely on is me.
