Okay, after having read this thread, and your intro thread, a couple of things jump out at me, sweetie.
Firstly, I don't think this is as much your fault as you think it is. And you thinking that is contributing to the way you feel. I'll explain why in a sec, but I feel from everything you've said that you're being way too hard on yourself.
Secondly... sweetie, you talk about the depression and anxiety you've been dealing with for a large part of your life. I've been in that place. I know how depression feels. And I know how coming out of it feels. I get the feeling that you don't trust the way you feel. You don't trust your emotions. Your instincts. And I get the nagging feeling that perhaps a part of this is that depression has made you question yourself.
To illustrate what I mean, I'll go into a little of how I have felt in the past. About 6 years ago, something happened to me that sent me into a downward spiral of depression. Very bad. To the point of several suicide attempts. I was in a very bad place. The depression scrambled my brain and made me feel at times like I was not capable of doing anything... but at other times like I'd had a dose of Novocain dumped into my system. I felt completely apathetic. Very similar to how you describe. Like I could write off anything I was feeling and just not care. This alternated on and off. In cycles a lot like you describe. Sometimes I would feel every emotion, razor sharp, and then it would go away and I would feel numb.
But, when... stuff didn't happen, and I had to deal with that depression, I got treated for it, and realised that it was the condition which was making me feel some of the things I felt. It was not me. It was something affecting me. And only when I came to terms with that could I start to heal, and actually start to trust my own feelings.
But for a long time, I didn't trust my emotions. Just like you don't seem to. You seem to have the same outlook I had. That you have to
know something, or there's always that element of doubt. When you have to rely on just the way you feel, and if something feels
right, I would always feel like "Is this really how I feel? Or is this something in my mind making me feel this way?" It's hard to trust yourself when you've had to deal with conditions which, by their nature, fundamentally affect how you feel and give you NO control over that whatsoever. It's hard to have that self-trust that you speak of. I totally get that. And I do not for a second think it's your fault.
I do think that as you keep on top of your depression and anxiety, and learn to listen to yourself, that whisper of your inner self free from the scream of the depression you've been feeling, that you may well build up that self-trust gradually. When you start to feel that your feelings are your own, you can start to listen to them and act on them more.
If you ever saw the movie The Lord of the Rings, or read the book... Depression is like Grima Wormtongue. He whispers in your ear, keeping you down. Keeping you believing things that you don't feel. And you don't feel ever like you have any control. Any self-belief or free will.
Being able to get treatment for that, and being able to clear your mind of those dark clouds and false whispers allows you to focus on how you really do feel. But it's like waking up from a really bad dream. A dream you felt so sure was real. And now you're not sure if you're awake or dreaming.
That's the feeling I get from your posts, sweetie. That's the place you're in. You're not sure what's you and what isn't. If you don't
know, you doubt. I get that. I know how that feels.
On top of the insight and advice given in this thread, I would say to give it some time, to get your head clear of the dark, twisting thoughts that come with depression, and see which instincts linger. Which don't go away. Which you can feel outside of that environment. That in itself may give you impetus to act.
In any case, I'd just like to offer a big *hug*. I think you know more than you think you know, you just don't quite know that you know yet. If that makes sense.
