Journalling has helped me to deal with figuring out emotions. Or finding someone you're comfortable talking to is another option.

Mostly trying to internalize the messages that your T has given you has helped me. So now I'll say "I'm worth it" even if I don't feel that way, because T gave it to me. Then I remember that she still cares even if she's not there.

Untangling emotions is hard and even if you want to just get it done right now - it might not be the best thing to do for you right now.

Doing mindfulness also helps, and learning how to breathe in a meditative way too.
