I think there's two sides to this:

1) there are things that friends just cannot help you with. I have experienced people trying to help me while I was suicidal. This is not something a friend can effectively do. It's also not fair to expect of from your friends. Yes, if I was suddenly actively suicidal, I would call my friends. But they cannot be there every day, every hour of the week, and holding that boundary in friendships is hard.

2) there are boundaries to being a T as well. If there's an emergency on Saturday, the earliest I could possibly reach my T is Monday, but that would be quiet a big deal. Otherwise it's no contact between Friday and Wednesday.

I think this all really depends on both your T and the environment besides therapy. If you have a good social life and struggle and get care from a good therapist, you're unfortunately more likely to be okay than if your friends or T suck.

There's good and bad eggs in every batch. I personally find therapy to be helpful, it's the only place I've ever felt secure in. I find that while sharing things with friends is important, I don't want to talk to them every day about all the bad things, I want to share the high while being open to talk about lows when it is required.
