That is true the past does really form a person into who they are. I have gone through so much and looking at someone else that has gone through the same amount or more really get me thinking about how I handled my situation. Knowing people that successfully pass hurdles help me to go on when I think its no longer possible.
By the way your username is interesting :P

Hey!
Thank you for taking the time to welcome me and to send me a message, it's always nice to speak to new people so I really do appreciate it
It's honestly okay, you don't have to be sorry, the past is all practice for the future and I like to believe that it has made me into a better person today.
Likewise, if you ever need anybody to talk to then I'm always here for you too
