they turn on me when the situation and the feelings become more than they expected and refuse to try to deal with it.

I can promise not to turn on you, but to be truthful, it's not me who needs to deal with whatever "it" is. I'm here as someone who is willing to listen if you want to talk. I'm here as support, but I can't fix anything for you and I'm not really here to give you any advice.

I can understand your hesitation to trust. I'm in therapy and it took me a very long time to trust and open up to my therapist. I've always found myself to be more honest on the internet because of the anonymity, but even then, some things are just hard to say out loud before you're ready. Still, I've found therapy to be very helpful for me precisely because what I realized more than anything is that I needed to feel understood and to be truly seen by someone. It's the hardest thing I've ever done, but it's certainly taught me the value of having someone listen.
