Please not again (sterek)

For the past 11 years after the hale house fire Stiles has been seen to disappear for hours on end. That had been going on and people never really cared since they thought that it was normal with his mental health issues, but once he left when Scott was having a meeting with Derek, he took notice. He didn't believe that is was normal for Stiles and wanted to help his little crush. Little did he know, Stiles was in a LOT more trouble then expected. Will Stiles be able to get help with his problem and have his crush of an Alpha help him or will it end in the worst way possible with Derek dead and Stiles problem getting worse?
