The metaphor of stopping a train barehanded is extremely accurate with how fighting depression and other mental illnesses can feel. It can feel like an uphill battle where if you stop fighting for even a second, everything comes crumbling down around you. I’m so sorry that the methods you’ve tried have ultimately failed you, it must feel so defeating to combat these thoughts again and again only to have them break you down in the end.
I heavily relate to how you said that your logic with depression is distorted. When I have my depression episodes, any positive thought I try to combat the negative ones with are quickly deflated by another negative thought. One thing I learned when doing ACT therapy was that idea of two wolves. One is positive thoughts and one is negative. If we fight the negative wolf, the attention gives it power. Therefore, we must focus not on just fighting negative thoughts, but putting energy and effort into our positive thoughts.
One personal process that has helped me when I feel as if the battle is me vs. me is to realize that the version of myself I am fighting does not have the tools that I have. My depression only has itself, but I have my family, my friends, God, and faith. Instead of trying to desperately fight it on my own, I take the thought captive and let it run its course and then leave. Depression is an illness that wants to leave you incapacitated, but if we keep our minds full of gratitude and utilize our support systems, we cannot be held down.
I found that having external validation from my family and friends helps me tear down the false truths about my identity that my anxiety and depression try to throw at me. I also have found that Biblical scripture calls us to cast our fears onto the Lord and remind us of how loved we are and how strong the Lord is in our weakness.
Logic cannot overcome our negative spirals, but the truth can set us free. Your identity and the very essence of who you are is what will carry you through this storm. You are loved, forgiven, and deserve to live. These are not logical arguments, but the truth. When the voices get loud, speak truths to yourself, speak “I am loved, I am forgiven, I deserve to live” and bask in the truth.
This battle is not an easy one, but it is one that will end in your victory. When the thoughts creep in, I know that you have the strength to take them captive and you can fight through this. I am so proud of you for how far you have come. I believe in you and love you my friend, keep fighting onwards <3
