It's a metaphor about ending a relationship. When you end an important relationship, the person becomes dead, and they still "reach for you". All the photographs seem to disappear, and people don't seem to care about the fact you loved someone. You're covered under "rain and thunder", a reference to depression. The "stains i've created" are the stains from breaking up with the person. The heartbeat failing is the person losing their feeling for love.
