@sun seeker - You are not worthless. You are a human being, and you have survived so much, and you are awesome. You are here, and you care about your friend, and you want the relationship to be good. All indications of you = awesome. I know, though, this is really hard, if not impossible, to see right now, so I am telling you straight.
Also, I looked at that thread, and sigh. This is a really nuanced issue, and I think that frankly people are so horribly abused by society's insistence that we must always control our feelings, that it's our fault if what other people do/say cause us to feel badly.
This is so cold and non-empathetic. And also makes no sense.
I think a lot of people don't have friends who can be totally with us when we are at our lowest. I am just f*cking lucky to find one friend (I mean, I have a handful I'd call friends, 3 who I'd trust deeply—but only ONE who I know can understand me that deeply) who is that awesome. Before this friend, I was so convinced that I had to work to keep the ones I had, that I had to take every pain that they triggered totally on me and NEVER tell them, because like, I totally had to keep friends. Right?
Here is the thing.
A true friend who triggers you, and you tell them about that trigger, will say, "Ah. Okay, I'll try not to do that any more. I'm sorry I triggered you. I'll do better in the future, because I care about you."
You see, in the strictest sense, no, it isn't their fault that you have this trigger. But they still caused you pain. INTENT DOES NOT ERASE PAIN. Are we playing a blame game if we ask them to not trigger us in the future? f*cking no. We are trying to make sure we don't hurt them AND they don't hurt us, thus improving the friendship and providing 100% more time for ice cream and movies.
To this date, I have only found one person who will do this for me. And they have also only found one person who will do this for them (and it is me).
Now, it is true that we cannot always share our most traumatic experiences all the time, because we both have limits in terms of what we can take any particular day and how traumatized we are, etc. We always set our boundaries—and we respect each other's boundaries.
But to me, this is the golden template. The golden goose, the golden cup, whatever.
This is the conversation that needs to happen repeatedly:
"I set this boundary. Please don't cross it."
"Cool with me. I have this other boundary. Please don't cross it."
"Fine with me. Let's go to Baskin Robbins and then see Captain America: Civil War."
And both sides must stick to not crossing that boundary.
Honestly, friendships where people hide their boundaries from each other and never tell the other when that boundary is crossed and causes them pain? They are lesser friendships. We can choose to accept these lesser friendships, sure, but we should NEVER EVER EVER say that those friendships are ideal in any f*cking way.
Anyways, if you need someone to talk to, I am here as much as possible.
