intense anxiety after therapy session, need help

salam, i had a therapy session last night where we went into some really deep emotions that i've been avoiding talking about (don't want to go into too many details). not even super deep, we literally just touched on it briefly. ever since the session ive been having very very intense anxiety. like genuinely i feel like my thoughts are spiraling, heartbeat racing and i feel incredibly incredibly overwhelmed. my stomach is sick and i feel nauseous. i couldn't sleep last night, but then eventually ended up falling asleep really late and then woke up around 3am, still anxious and spiraling. i was going to take a sick day, but then eventually fell asleep , actually overslept and then needed to rush into work. i'm currently at work, still feeling anxious and sick to my stomach even though its been 12+ hours since this session. i don't know what to do. i don't have anyone in my life i can talk to about this, so i just needed some support. is this normal after therapy?? should i tell my therapist? i was thinking of texting her but i remember her telling me not to text her between sessions. however i have sent her some things in the past and she responded like 2 days later. can someone help me
