Finding my footing

Returning back to work after a long time is a strange feeling because (as expected) people and things seem to have moved on - without me.

• People have become used to not having me around 
• Ways have been found to get things done without me 
• Some others have taken over stuff I used to do

It's business as usual for everyone else. It's me who needs to find my place again amongst my team - where can I bring value (if so)...it takes time. After all, its true that nobody is indispensable.
