When I was 18, living with abusively behaved parents, I believed there was no help, as I was told only pregnant women get council houses.Again there's a substitution of "attracting" for "noticing". Your worrying is unlikely to cause negative things, but rather to make you more sensitive to notice and dwelling on the negatives that do come along.
I've a friend who goes through bouts of black depression in which the world, life itself is full of negativity in his perception..im talking about the injustices he sees in the news. In his darkest periods he both dwells on, gets angry about, and draws attention to these things. He sees them as evidence of the world and life itself being a terrible thing. I live in the same world and it doesn't look anything like that to me. His mood affects his perceptions and the things he gives his thoughts to.
In short you've nothing to feel guilty about. You didn't attract any of the bad into your life. But you may or may not have some say in the weight you give to it. If there's a way to appreciate the positive stuff and put the negatives in perspective, the world will suddenly seem a lot less stressful place.
I had a lack mindset, had I of reached out for help, I would have got psychiatric care for depression and a paid for flat, and a base to train for work before diving into it before I was ready.
Due to my limited lack mindset, I dived into work before I was ready, abuse interfered with concentration and I got multiple sackings from jobs.
A more positive mindset would have got me psychiatric help, support with paid for council modest flat, time to train to do office work, and get more confidence and no sackings.
