Is there a way to get back my session. i logged back in with the same username and i see that my session is still there
admin@ljaco-srx-vip> configure warning: Clustering enabled; using private edit warning: uncommitted changes will be discarded on exit Entering configuration mode Users currently editing the configuration: admin terminal p1 (pid 55661) on since 2011-12-19 21:43:26 UTC, idle 00:41:46 private 
is there a way to get back to my original session or get the config back that wasn't committed yet?
I don't think you can recover the changes made by a lost configure private connection, at least in a human-readable way.
configure private uses a private copy of juniper.data file instead of the shared candidate config (juniper.db) and is stored in /var/rundb/private until the user does commit. (This is one of the reasons why you can't go into configure mode while someone else is using configure private.)
The temporary file in /var/rundb/private is stored as a binary data and not plain text, hence my doubts.
I would recommend disconnecting the stuck session using request system logout terminal <terminal-name> and start from scratch.
