I see how this seems totally unfair. I agree with Onward2wards , keep searching for the right support system... people need people, and it's, as you've experienced, difficult to find reliable supportive people sometimes. Maybe try to stop the anger and guilt by forgiving...(Do it for you, not for them) practice forgiveness to release those bad feelings that you don't need on top of what you're already going through. Forgiveness helps me switch my energy from remembering past betrayals, to be used for more useful things. I hope this was helpful.
