Yes, things can change. After hard times in life always come the good ones(usually) when you are ready to leave the past behind you and move on............. ....but the question is...when am I ready?? It's not that easy to forgive people who said things to you that did hurt you. It's not that easy to forget the pain that you carried with you for years....When the right time comes around you will be ready for a change.
Sometimes you just need to say: "FUCK IT" .. forget the pain, the suffering and the harm that you were faced with in the past, and live on 'cause that's the right way to choose when you continue your life. NOW!

Do not put off things until you are totally exhausted with everything that's goin' on in your life. It's better to get it over with right away. ( I do put off things very often. I shouldn't do this. I know this makes everything worse and for the future I don't want to live like a lazy person whose life is exhausting for. I want a change. I need a change. I'm changing. I'm not sure if I believe in God, but I'm sure that I believe in something butI know that there's something which helps me to change and keeps my head up and pretends myself not to give up)  
You'll find your way to be happy after a while. I believe in that like I also do believe that I'll be happy, truly happy some day.
