i want to say something that could help, but i don't really know what to say.
i know that feeling of helplessness, that everything is going to stay the same and it won't get better, hurting myself because i'm causing myself all of this pain. its an experience of being isolated and alone, who can relate? and how could i relate to them anyway when i feel like i have no energy to give.
i think people that are sensitive to feeling their emotions, it can be easy to get stuck in a loop, of suffering. there is a lot of it around, so much hate and violence, it can be a task to not catch the bug.
how to change your habits and patterns of reacting to your thoughts and feelings. it starts with small steps, small steps in a positive direction. that could be a nice word to someone, hug a friend and tell them how much they mean to you, doing something that gets you out of your head, connects you to other peoples experience.
i often think of depression as a pair of really dark tinted sunglasses, until you take them off, you forget how much light there is outside, and also how temporary everything really is. it can be like starvation to not have those moments where you get a breath of fresh air, and that air tastes good!
if you are honest with yourself, and can start to take off little bits of armour that you surrounded to protect yourself during a traumatic time, when you felt really vulnerable and unsafe. you have all the answers, but it is a long and gradual road to freedom, the adventure is part of the delight though. i think you still have people that love you, and it might surprise you how much they care for you and want to help.
be well friend.
