Season Ended Mid Session

Ok so the season ended last night in the middle of me and my buddy playing. As I have said in my past posts I am just not getting into seasonal characters so forgive me if this is a stupid question but, since it was mid session is all my gear just gone forever? Also does my stash equipment share through seasonal characters or is it also gone because the season ended? Again I’m sorry if this is a dumb question I’m still figuring things out. Thanks in advance!
