LA-ML - how are you doing? I can empathize with flashbacks/needing to reach out to someone, feeling panic with fireworks, etc. It's too bad the hotline could not have simply given you some other resources to use; laughter is not an appropriate response to pain and suffering.

Where I live, we have "warm lines" run by NAMI. You can talk about problems, or just chat. During peak times, there is a 20-min limit by necessity, but they usually provide other resources. Yes, occasionally you get some totally unqualified person ( defined as bored voice, lacking in empathy, repeating canned sentiments), but as most workers are also m.h. consumers, you usually get valuable feedback.

If you can wait a bit (approx 24 hours), the Samaritans in the UK have an email service. I write out my problem, helpful just to get it out, and get a pretty measured and helpful reply. Link: Samaritans | Samaritans I'm in the American states, but still find them helpful.

I'm not sure if you use RAINN, but they can also be a great resource: https://www.rainn.org/ I have called them many times (my incidents were over 10 years ago, and they are still compassionate.)

I've found the PTSD and Anxiety forums here very helpful; there is a Survivors of Abuse forum as well. I don't see one specifically for Sexual Assault (?) maybe someone can advise about this.

Apologies if these are things you are already aware of. Hope you will post again to say how you are feeling, what has helped.

Take care
