You are NOT NOT NOT messed up. We've all had different experiences.

Some of have trust issues, where it's hard to be completely honest at the beginning of things - we all go at our own pace. Some of us are more of an "open book" in therapy than others as well.
I know, that for me - when I click with a T, I become a blabbermouth. So telling people (not just Ts either!) everything on my mind all at once.

Sometimes it seems to surprise Ts - but I've seen ... 4 Ts in four years (give or take) ... I'd rather just rehash the stuff I already know about myself, and work on what I don't know about myself.
Does telling T everything right away bother you as your own behaviour? Or are you comfortable doing so? Do you regret whatever you've said afterwards to your T?
If it doesn't bother you, if you're comfortable doing so, and if you don't regret going the speed you're going with your T - then don't worry about it.
It's your therapy, and you shouldn't compare it to anyone elses.
As for me - I admit I'm a bit quick to go through some things because I want to be "cured" sooner rather than later - so I'd rather rush than process stuff. So I'm trying to not force myself to go so quickly. But whatever works I'd say.
I'd say being so open with your T must be a real blessing - it's nice to connect with someone well
