Onto the topic of technology; I'm going to give you a couple of high-level words and phrases that you can hopefully use. I would say, “I can't do without, or I can’t manage without,” for instance, “my cell phone means a lot to me I can't manage without it! It accompanies me no matter where I go. Every time I turn around, there it is! My cell phone I go grab it.” So, I can't do without it; I can't manage without it. You can use either of these phrases to show how important something to you is.
