RTS, it takes time, and if you rush it you will hurt yourself (speaking as someone who tried to do that, and learned the hard way).

Walking through that time line was useful for me because it spun out the movie reel of my life in a linear fashion - it showed me the accretion of pain and experiences that had brought me to where I was when I started therapy - amazing once it was all put together -

and because of the time line I remembered a hugely traumatic event that had been completely repressed. I was SO. SHOCKED. that it could have disappeared from my memory so completely. I assure you, just one day before I remembered it, if you had asked me whether such a thing had ever happened to me, I would have very confidently said no.
and then... wham.

it helped me; others have things to tell about which helped them. You & yr T will find your own way. Just go gently
