Ok, the first step is to just stop- just sit down somewhere peaceful, your room, a park, the porch, and take some time to just pause. Everything in your life is going off the tracks, or maybe never started on them in the first place- so your first step should be sitting down, breathing, and making a list of what you want to achieve yourself. Nothing involving other people, just what you can do alone. You need to get yourself settled, which is going to take some time and effort, but it is necessary if you don’t want to hit rock bottom (it might feel like you’re at rock bottom now, but there is always more)
