Super anxious about work and finances

This is hard to type, but Im feeling like Im worth more dead than alive. Right now my job (sales and 100% commission) is not going well. Ive actually left the company before and came back 5 years ago. It is my home and I enjoy the people but I really cant handle the roller coaster of the business. Its eating at me especially when things are tough like they are now. On top of the stress of not making money our property taxes increased and my mortgage has increased by 700/mo. (It is already high). My wife works too, but her company is going through lay-offs so there is uncertainty there. All this stress and panic it makes it hard to get out of bed. I constantly feel like I am faking it and I feel like I cant do it anymore. Im at a breaking point. I think if I was in an accident or if I had a disease that killed me my family would be better off. I know that really horrible and I should be thankful for my health and that I have a family (and I am) but the cloud of debt is hovering above and the anxiety is so high. Im on anxiety meds, I do tapping but I need a quick fix. Please someone tell me Im not alone.
