Is there any chance I can get my account back?

I was playing on one of the servers a few months ago and I decided to take a break due to personal reasons.
Recently I decided to return to this server and I found out that all my characters have dissappeared, I dont quite remember what server I played on and what stuff I had on those characters but I remember having quite a bit of stuff. Is there anything you can do to get my characters or at least any of my stuff back ?

Please try to do anything, I'm really interested to play again but the thought of having to start from the begining without anything after all this time of me playing kinda annoyes me.

I can add a screenshot of the stuff I bought with the points that I collected, could you at least be able to give those back to me.
