Do you guys find it almost impossible sometimes to apply therapy lessons to real life?

I am feeling SO SEPARATE from all of my friends right now. I feel lonely. I can't even find half of them. My brain immediately goes to "they're all together somewhere, no one wants me around, etc" and even though the LOGICAL part of my brain can see that doesn't make sense (we haven't had a fight, I know people liked me the last time I saw them), the emotional part of me is FREAKING out. I am so lonely.

There is an event tonight for my two youngest that I really don't want to go to but I am forcing myself so I can see some people and hopefully make this feeling go away.

My needy mom is about to drive me over the edge and I can't set boundaries.

I know these are all things I've learned or I'm learning with T, and I feel frustrated when I can't apply them in real life. And I go to therapy and there's so much CRAP from the past to work on that it almost feels like a waste of time to talk about stuff that's happening now.

I feel like I should be able to find my way out of this. I don't even know why I feel so lost and alone.
