<human>: As the title says, I have found my biological father's wife and daughter  on Facebook. He had an affair with my mother 22 years ago when he came to Canada on business from Florida. His wife is the one that phoned to say they wanted no contact with me anymore when I was 2 years old and I haven't heard anything from them since. 

After a Google search using only his name I was able to find extensive personal information. I have two younger half sisters, one of them looks almost exactly like me. I now know their address, the business they own, and that his wife was arrested for retail theft over $300 last year (mugshot and all). I even know details about their home including how much they purchased it for and # of bedrooms. This is just from a Google search, I didn't sign up or pay for any information.

After discovering that they own a business as well as paid over half a million for their house, I feel even more abandoned and betrayed. He left me in poverty with a dysfunctional single-mother family. I spent most of my teens mentally ill and unstable because of my upbringing. If I wasn't waking up on a stranger's couch or in the mental ward, then I was in emergency recovering from an accidental overdose. I'm starting to recover from the mental illness, but it is a daily struggle to try and get on my feet and create a life beyond this without a real foundation.

<bot>: My dad abandoned me, only to leave me to a life of poverty and instability while he was living it up. I found his family 20 years later.
