Wow, that's a session that's chock full o' stuff. You've obviously hit a rich source of feelings in exploring your memories/relationship with your brother.

Sounds like you have a lot of questions and feelings left unresolved from the session. Maybe you could write some of those questions and feelings down, and take one at a time, very slowly, with your T. They are obviously powerful, and you deserve to release any guilt or pain or anger associated with them.

Be gentle with yourself, this is heavy stuff that touches you in many ways. You're doing great in continuing to work through it; don't push yourself to figure it all out at once.
