Honesty, even negative honesty, is so welcome here @Till23 I am glad you feel like you can be vulnerable here.
I can absolutely relate to that trapped/unable to relax feeling. It can become all-consuming at times, and the internal conflict between feeling both restless and frozen is really hard to sit with. I think sometimes for me, SI will hit during those moments I feel most trapped - my brain is seeking any way of escaping my circumstances, and with extreme feelings comes extreme measures of dealing with them. I think my brain at one point formed a habit of reverting to those thoughts during times of intense duress, so it would become automatic even if I knew logically it wasn't something I was actually considering. Can be very painful and scary to sit with, that's for sure.
Sometimes with helplines, even if I don't think the actual conversation is going to do anything to change my circumstances, I know that heightened emotions always fade with time, so it can always be a backup option to consider - even if it's just a way to get closer to bed time without having to sit alone with your thoughts. No pressure of course, just food for thought.
You have nothing to apologise for. What's that saying, a burden shared is a burden halved? If it helps you to get it off your chest, then it's nothing that needs an apology. You may of course edit to your heart's content if that will help reduce anxiety - it can be overwhelming to feel 'exposed' when we're open about how vulnerable we are.
I am happy to flick you an email to help you safety plan and stuff if that's needed at any point tonight hun - you just let me know 💜
