Oh, I am so happy to read your message ~ for someone so young, you are exceptionally wise, and your instincts are excellent. Your positivity shows that you are resiliant and don't want to be stuck in the role of victim, and that is SO IMPORTANT -it means that while your physical self may have been mishandled, your soul is undamaged, and you will never be down for long. You are quite a strong lady, whether you know it or not. And it's never too late for change. In fact, the very second that you WANT to change, you already have, because you've changed the energy around you. You see how everything changes for the better as soon as you start to think positive and act positive?
Always remember: you attract what you want into your life by how much you think about it and how much emotion (and what kind) you put to the thinking. Angry/sad/depressed emotions will create angry/sad/depressed energy and that will bring angry/sad/depressed things into your life. People will be difficult, events won't turn out as you wished, etc. If you want to bring good things into your life, create a mindset of whatever makes you happiest and ground yourself in that. Then, focus on that place and feeling, and ask for what you want, and you will create positive energy and call positive things into your life. It's one part joyfully thinking what you want, one part believing with certainty that it will come, and one part knowing that you are deserving of it all. Then all you have to do is let it in. It's really very simple (just keep in mind that just because it's simple doesn't mean it's always easy!). And it only works by believing.
Your husband sounds like quite a terrific guy and together, you sound like a great team. If in some small way I've helped you see what you already knew on some level, I am so happy. I think you're going to be just fine
