By all means, please contact your doctor and/or your therapist. You definltely need a break. No killing people. If you really have to, then see about checking into different living arrangements, even if that requires being in a mental ward for a few days. There a social worker can help you look for different options.

We are here for you. Get away to a library, a park, or someplace quiet when you are ready to explode.

My thoughts, anyway.
