pacific,
I find personally that we have enough to deal with without pushy Ts. The thing to remember is that they work for you to a certain extent. If it wasn't for us they would be out of a job. You are perfectly within your right to agree or not agree with the T's suggestions. Try to stay on the polite side of this though so as not to piss them off.
We are not wrong just different - dare to be different. And if left alone with a few books on the subject, most of us would manage just fine.
What's "normal"? There are all kinds of crazies out there who are not thought to have a mental illness. I've lived with this a long time and it is quite simply a part of who I am now.
You don't have to make any of them 'visible' and you can talk to them in your head. They say addicts are good liars. Right? Well we are good at covering up for alters. It can be your secret, if that's how you want it - or not - the choice is yours. I have family and friends and only two people know about my 'stuff'. The rest just think I’m prone to some serious bouts of depression.
We all have what's called internal dialogue, we have conversations with ourselves; thoughts run around in our head as we decide what to have for dinner or make plans for the weekend. Alters are a bit different and some times a little more difficult to describe but it's more like a real conversation with another person and not with ourselves. But it is still in our head. But some of the effects can be seen in the 'real' world; like in our moods, the clothes we wear, the food we like, the people we like. If we are dealing with alters, all these things keep changing. Sometimes we are aware of it and sometimes we are not. If you're worried about other people noticing, you can always cover up with excuses.
It's important to find a T who has some experience in DID. Or you could just learn about it together. Avoid letting the T's reaction get to you. Just keep reminding yourself that the T is leaning too.
Working through DID may take years. If you want that kind of help then you need to be prepared for the long haul. In my book there is really no need for the T to get to know the alters. You may not agree and that's fine. But I found it simpler if I were the one who goes to therapy and work to make some sense of what is happening and why it's happening. Going over things with alters later helped. I will say though, if an alter feels strongly about talking to T, I think I would try to fix for this to happen. All said and done the real important thing is to keep your 'family' or 'collective' or 'system' comfortable, satisfied and feeling safe.
I've read a lot on this and I've yet to come across anyone who wanted integration. I think we work well together now but it hasn't always been like this. In the beginning they drove me half mad, my 'real world family too. As things settled down more and more over the years they came to resemble a bunch of warring siblings; a lot of shouting and screaming but no real damage or hurtfulness.
As for being alone. I did it once. I haven't really told anyone about this. But once, when I thought I was really cracking up, I ordered them to go away and leave me alone. They did or at least they seemed to be gone. I had never felt so alone in my whole life. The quietness was deafening. I just sat there rocking back and forth with the tears running down my face and thinking, Oh God! What have I done! I seriously felt like an empty eggshell. Then I found myself apologising and asking them to come back. I really thought I was going mad. Things went back the way they were. But after that, I found I had a lot more control than I thought I had. And from that day on things got much, much easier to deal with.
I suppose you could "hamper" your own healing. But I think it depends on how much information you arm yourself with. Getting out of our own way sometimes might move things along but the more you learn about yourself and the disorder the better.
Don't worry about the questions. It is a support forum after all. And what we write for each other is also helping others on here gain more information too.
