@Anais V - No problem! Yes, whether the thought is a question (am I suicidal?) or a statement (I am suicidal), the technique stays the same.
The content of the thoughts really don't matter that much. We have thousands and thousands of thoughts every day, many of which are entirely inaccurate, but we don't notice most of them because we don't care. As soon as you start to care about a thought, you put a spotlight on it, and it becomes all you can focus on.
An example I like to use is thinking about what you're going to have for dinner. You can have the thought, "I'm going to get a salad for dinner because I want to be healthy." Then when it comes time for dinner, you could end up getting a pizza instead, because that's what you really FEEL like eating. The feeling of wanting to eat the pizza, in this case, was more powerful than the desire to be healthy. On the flip side, you can think that you want a pizza, only to get a salad, because for whatever reason you really feel like being healthy that day.
In this example, your thoughts simply did not line up with your eventual actions at all. But we rarely notice or care about cases like this because the consequences are so mundane.
These inaccurate thoughts are happening ALL THE TIME. It's only when they happen to involve something we deeply care about that they can become sticky intrusive thoughts. That's why "I want a salad" is never an intrusive thought, but "I want to kill myself" is so hard to ignore.
That's why meditation/mindfulness is so helpful for this, because it helps us detach from the hamster wheel of thought, and gets us deeply in tune with our feelings and emotions, which are the things we actually want to listen to. If you truly feel depressed, you can get help. If you truly feel sad, you can process your grief, if you truly feel anxious, you can address the cause of the anxiety. There's no need to get wrapped up in the thoughts and the stories that the mind creates surrounding the emotions.
