Welcome
What kind of therapy your T practiced? Some schools believe that it's not about the past so they focus more/only on the present. I'm no expert- prob some client-centered therapies? Psychodynamic therapy for sure.

It's great that you've decided to give therapy another chance- though I don't understand why have you decided to take 3 months break?
I do understand your anger at wasting 1 year of therapy- but some of it still could be useful. I remember going to group therapy - everyday, 8 hours for 2 months. Hated it- truth be told I didn't want to go in the first place but my parents/Pdoc made it kind of mandatory. It didn't help me then (though the group T told me that I wasn't ready for sharing my story with others yet and to start individual therapy instead- I'm still really thankful to her) However, now nearly 7 yrs after I do sometimes think about the ppl I was there with and I can relate to some of their troubles and the way they have (tried to) overcome them.
