Yes, they do affect your life forever and you will never be the same person you were before. But time will help and hold on to that thought with everything you have right now. It takes a long time for the shock to wear off and to figure out how you fit into this severe change in your life. If you can find a good therapist I suggest doing so. I didn't and wish I would have. Ask me any questions in comments if you need more help and I will try my best to help more.
I get the gist of where you're coming from, I lived in my fiancee's floor for the last 10 months in hiding and I have PTSD from it. I would definitely say recent trauma can effect your way of life. Just remember, tomorrow is another day and the past is the past. That's how I cope.
