Hi,
I don't know you, so don't know what friction you may have here in the past, nor do I care about that. I can sympathize with your situations, coming from a family that had depression issues, having suffered minor depression (but not like you are having), and having panic attacks that started 10 years ago that I still have to take medication for, or else they come right back.
From your post, it is hard for you to reach out, but please, please call your doctor back and tell them how hard of a time you are having. There is no shame in it, this is not something you picked or chose to have happen. You doctor can hopefully get you in with a Psychiatrist promptly, who may be able to better target medications to help get your feeling better faster.
Please know that there are people out there who completely understand how you are feeling and how hard it is to see that this will pass. Take it one step at a time reminding yourself it will get better, because it will.
