You can't "force" but you are still there, just hidden. Working with your T will gradually uncover you. I felt like I was buried under a bombed building like some old WWII stories of orphans, or a mudslide/earthquake or other natural disaster. Eventually the rescue people uncover you by working toward the sound of your voice.

Keep trying, starting with very little things where you are. Did you see "Runaway Bride"? It's like when she tried all the kinds of eggs to see which she preferred. You have likes/dislikes, etc. but have to get reacquainted with them. Try something like that, start with "food" and decide what meat and how recipes are prepared, etc. you prefer? Keep "doing" things personally and hopefully eventually something will trigger something else. Triggers aren't at all pleasant but can be extremely helpful getting better. I remember (and laugh) my T was saying how since I liked cooking I should do that since there weren't likely to be any triggers in the "kitchen" and the kitchen should be "safe" but there turned out to be all kinds of unlikely things going on while I was cooking from peeling potatoes (I was extremely slow and my stepmother would criticize and I hated peeling potatoes and comparing myself to her quick sureness, etc. so I rarely made mashed potatoes for my husband but "suddenly" found that the more I peeled the better I got at it so it wasn't that I was slow/defective, it was that I had been a child and didn't have any experience!) and once I was making a biscuit recipe and got all "gooey" which I hate :-) and without thinking was "wishing for my mommy" (in a funny/joking sort of way) only to realize to my horror the one-two punch that my "mommy" was dead and my stepmother (backup mommy) was at that moment/that day in the hospital getting a CT/MRI scan of some sort (my mother died of a brain tumor and they didn't have those scans back then -- maybe she wouldn't have died if they had and they could have seen what was wrong with her sooner). So, all my "mommies" were not available and I had icky hands and burst into tears. I was only 49 :-)
