Warning suicide mention:
I messed up a suicide attempt really badly and it caused me to have retrograde amnesia for a long time.

So i made a deal with myself and the past version i no longer knew to never attempt it again as they didnt deserve to cease to exist for the pain they were going through.
Now if i am feeling truly that level of depressed i reach out to at least 3 people that care about me. It reminds me that i have them and they usually help me through.
