I don't really have anything profound to say about depression that no one has ever said before. Or the eating that accompanies it.
But I can relate to having suicidal thoughts due to depression, most of it I attributed to my parents growing up.
This may or may not help. I know it sounds completely loopy and I am NOT in any way religious, but one thing that SERIOUSLY kept me living was the revelation that I had probably signed a spiritual contract to be here. Trust me, I am not saying this merely because it sounds cool and it is something that I want to be true. I don't want it to be true...but... I think it is. Loopy. I know. But what if?
It is a long story on how I arrived at this conclusion and it will certainly sound strange but the point is... this is what I believe... and it is NOT what I WANT to believe. They are separate things. I wish the whole relationship between life/death/souls/physical reality were different... but I cannot deny the unfortunate pattern that is the best fit in my mind on how things work. Which means... we repeat unlearned lessons.
And I even know what my lessons are for this life. I have 7 of them.
And while I could break my contract via suicide, I would then be required to repeat my lifetime, or a similar life with the same struggles, all over again. And it would be harder because there would be new lessons attached to it. So ending my life isn't actually ending my life at all. It is just making it harder in the next one.
Now... if you hate living so much... is suicide really a solution? Nope. Bummer.
So, if you are feeling particular edgy one day then ask yourself just What If? I certainly don't want to risk it.
