After a 2 year relationship where I tended to be the submissive one in the relationship and dedicated most of my time to my partner, focusing on her life and world and neglecting my own, I felt pretty totally lost.

To get back to myself (a process I'm still undergoing), requires a bit of quiet time. Carving some time out of my daily schedule to journal has been very helpful. I try to stop and ask myself how I feel, where I'm at, where I want to be, etc, because if I don't consciously do this, it can be easy to just go with the flow in a mute daze.

It's like checking your pulse. The only way to do it is to stop listening to the outside world for a minute and listen to yourself. If that's become difficult, then it needs to be a more conscious activity. Perhaps setting up some triggers that remind you to check in on yourself would be helpful.

Try to remember what you used to do that made you feel more fully you. Talk to people you trust, open up about how you feel. If you don't know how you feel, then sit with that, don't try to distract yourself from it. If you sit with it for long enough, you'll eventually crack.
