Let me start off with I'm probably as bad off as you are. Somethings I've been through are similar, while others are completely unrelatable. All I can offer is this. So long as you have hope and push for a future, one that is completely within your power to achieve, you can have. Relationships require two people, so no amount of advice can help, but being careful of who you let into your life, can help keep some of those problems in check. As I said, I'm far from the right person to give advice, expecially with where I am in my own life, but hope is a very powerful thought and it can get you through some of the toughest times. Goodfriends help too.
