<human>: Can you condense the text into three sentences or less?

Hey R/relationships, last week I made a post about feeling lost and confused.I spoke to a counseling service over the phone who then reached out to therapists in the area to set up a meeting. Last wednesday i got an appointment. Turns out I have a verbally abusive brother 20 and an anxiety disorder. At the end of session therapist says she will cal me thursday or friday so we can have several immediate sessions. 

Saturday i havent heard anything, so i called and left a voicemail and a few hours later sent a simple text reading, "Hey, will it be possible for me to have another appointment soon?" Nothing.

Sunday still nada.

Monday I call a few times during the day and leave one voicemail. Also sent two texts just asking for when i could have another appointment. These are all spaced out over the whole day. I wasnt bombarding her and I was trying to be super polite. Nothing.

Last night I have an incident with my brother and call the 24 hour counseling helpline my health insurance offers. I am talked down from my state of panic and upset and the counselor says they will find me another counselor this week.

Today suddenly i get a text from the therapist last week, "Hey I am totally booked and am waiting for someone to cancel so i can offer you that spot. Which is very likely."

Is it irrational for me to feel angry that after saying I needed immediate help and that she would call me thursday or friday last week, that i heard nothing from her after reaching out over the weekend? Should i go to her when an appointment opens or should i go with some one new? How do I respond to her text?

Thank you in advance for any help.
<bot>: New therapist waits almost week to respond to text and voicemail after promising to get back to me in a day or two. Am i right to feel upset?
