As long as you're here looking for help, you're not beyond it. Some things may not have worked to help you in the past but there are still options and doors open to you.
Having a support network both online and in real life is important, which is why SF is great, and you know you can PM any of us at any time and we'll lend an ear. If you haven't already, though, speaking to your GP might help as well. If you're struggling and need help, there are lots of people out their whose job it is to help you, and speaking to your GP about it might clue you up on who and where they are, and what they can do for you.
Life might seem unbearable, and it might seem that it won't get any better, but as long as you're alive and fighting there's the very real chance that things will get better.
