My therapists apology

Last week, on wednesday, I texted Eileen.
I was in a bit of a crisis. I texted her telling her how I was feeling.
She never answered my message, which is totally unlike her. I decided not to text or email her again. I was kind of upset at her lack of response to me, because I really needed her support.
A few minutes ago a text came in from her.
She apologised and said she was sorry she didnt answer my message, she said she regreted not answering it and she’d understand if I was feeling angry at her as she’d let me down.
She said at the time it came in she was preoccupied and not in a position to answer me, and then she just forgot about it.
I’m not angry any longer now, I’m over it. So I texted her back and I said it was fine, that I understood.
I know tomorrow she’ll probably spend a few minutes of our session talking about it. I also know when she apologises, her apologies are heartfelt.
I understand she is human, and she also has a life outside of being a therapist. Who knows what was going on with her, it must’ve been something big to say she wouldnt have gotten back to me.
She’d never have not gotten back to me on purpose, I know that.
I’m happy she took the time to text me this evening. That means a lot to me.
