Self-Pity is such a hole that we dig ourselves into, it can become hard to bring ourselves back into an objective frame of mind. The tendency to wallow and slink further and further into it, actually begins to have it's own twisted allure on a sub-conscious level.

We feel bad, so we sink in the feeling, numb body and the mind with stimulants, food and excessive junk media. It feels better than dealing with the problems head on, justifying our hedonism as a comfort rather than part of the problem.

But in doing so, we sabotage any hope of reconciliation whilst we allow these these negative thought patterns and behaviours to dictate our life.
People can identify so heavily with the mindset of victimhood, it becomes increasingly hard to let go.

The writing, and speaking out loud of affirmations as you've wrote here though, is exactly the remedy to the problem. Although, it takes a strong will to be honest enough to engage with this sort of work.

But they're a truly powerful way of declaring your true intent and broadcasting it to the universe.
