Suicide rates are much lower in areas where people have less access to things that can end their life (e.g. https://www.hsph.harvard.edu/news/magazine/guns-and-suicide/), statistically speaking many people do make it through. By offering euthanasia to people who would otherwise survive, those people will lose their shot at life beyond their condition.
Public health policy has to be driven from the net benefits to all and not at the individual case level.
That doesn't seem to me to be a reasonable standard for medically-indicated euthanasia. Influenza meets that test more strongly.
I do wish you the best in your future path, however long that may be.
That's beside the point in that the current medical practice and legal environment doesn't support that position broadly, so with respect to medical indication, the fact that some people die from a given condition does not seem to be a workable threshold for supporting euthanasia as a treatment.
Here’s a link to a recent Reddit comment where I discussed this idea, along with suggestions of drugs to try:

I'm sorry to read that you want to die, but I hope very much that you continue to fail. You are valuable, you make the world better by being in it and it will be worse when you do die. Yes, you have a mental condition, but that is no reason to hate yourself: you deserve love, not hate. Life is tough for everyone, some more than others, but it's also full of joy & beauty, and you're part of that joy & beauty.
