When u work with a senior or colleague who guides you, when he leaves company do you feel weird , like anxious how younwill handle it alone

Forget senior or colleague.... ,, i feel sad when juniors and freshers leave... they are able to find a job, and am stuck here in the same cycle..."same shit, different day"

Every senior should guide juniors.. It is part of their job.. And looking out for individual goals is a personal choice. Both can happen.. Many factors influence these decisions. Northing weird. You might be new to this. It's common!
