Need Help Please

I’m feeling at my lowest point and I need help please. I don’t know what to do, but I know I need help. My mind is a mess and I can’t do anything. I couldn’t go to work today, my chest is aching worse than ever and I’m tired I can hardly keep my eyes open. The attack will pass. Have to keep breathing softly. But my mind it’s so bad and I’m finding it hard to control the darker thoughts and my personality disorders are acting up it’s like having a billion people in my head all at once. I’ve phoned my doctor and my therapist both aren’t answering. Has anybody else experienced? Please help me I need help with this asap. Lora.
