On behalf of a friend he needs some advice

Okay so this is a legitimate "I'm asking for a friend" he's new to reddit and well to save him some time for his post getting approved yadda, yadda, yadda (Seinfeld quote for those Seinfeld fans) Anyway so here is his question PS: I'm giving him this link so no need to say "tell your friend". Anyway thanks guys.I am writing this long message for some advice, As I haven’t had the easiest childhood, So Let’s start.I am a young 26 old gay man, unemployed and single, I moved to Australia in 2002 with my step dad, brothers and mum from England. My Mum and Dad got divorced when I was very young of age In 2005 my step dad died from a heart attack that I witnessed and think about every day and miss terribly, a few weeks after, a man on MSN was talking to me, and was grooming me, when my mum found out and the Police were involved and arrested him as he was a wanted pedophile, I was caution, although when the Police told my Mum I was gay, as she hated gays I was kicked out of age 15, I was raped at age 16. As my mother sometimes would give me $10.00 a month for food at the time. Centrelink wouldn’t supply me a payment for food and living so I was living on the street and ended up in hospital because I felt really sick and weak, because you could see my bones. They gave me some food and I kept vomiting up. After my mum said she didn’t want anything to do with me and won’t be supporting me any money I was approved for a Centrelink payment for food so I was able to get better over time. I was living with my partner (at the time) and his family for a few months, I was forced out on Christmas Eve because I had tonsillitis. (Yes It sounds crazy) As I planned to have my dog picked up a few days later because Jet Pets couldn’t pick my dog up til the 28th Dec, they were going to poison my dog and take him to the pound. I had to give up my dog because I was forced to move and had no way to go really that was stable and was unfair on him, I miss him so much, as he was my best friend in the whole world every time I talk or type about him I start to cry, as giving him up broke my heart and still does. I wish I could get him back as I am in a more stable house now but miss him a hell of a lot.I suffer from social anxiety, depression and anxiety and I am suffering from dyslexia. I get paranoid over things every day and worry too much about things. I find it hard to find a job because of my depression. I’ve had relationship, I have been cheated on, used for sex, used for money and one of my ex-partner is dated one of my friends which I haven’t spoken to in year which pissed me off.I always try to help people out and hate to see people suffer. Recently my partner broke up with me and I ended up in hospital for depression because I was suicidal, We’ve been together for two years, like my ex-partner needed money for whole new car tyres because the police took his car off the road and had no money and meaning I wouldn’t be able to see him, so I paid for him and promised he would pay me back and has only paid me $75.00 back and has blocked me and doesn’t want contact with me for some reason no idea why really. I have no support or anything because I wasn’t allowed friends. My ex before that needed $350.00 for an Xbox layby as he would lose the payment he has done at EB Games and would pay me back and I haven’t seen a cent back and that was 2 years ago. I am mainly looking for some information on what people can suggest with the things I suffer and have dealt with through my life.
