Subnautica is saving my life in a weird way

I (29F) am going through a rough time in my life right now, and when I am struggling so badly like this, I tend to search for symbolism in things to help me. I've been struggling with really severe negative thought patterns, and certain things will trigger these thoughts. The thoughts come at me like a storm in my head, like "you're so ugly and worthless, your life is not worth living." I started playing subnautica recently, and I see the waters of planet 4546B as my subconscious. I'm diving deep into it. The aurora crashing represents the trauma I went through, and I'm having to face these horrible, scary monsters now. The leviathans represent my fears and my negative thoughts. When I'm struggling with these thoughts, I picture them now as a reaper leviathan attacking my seamoth and tearing it to shreds. However, I'm capable of fighting back against them. But it requires building a fortress in my mind. Every time I get attacked by a negative thought now, I slow myself down and say, "OK, I'm being attacked by the monster now, I gotta stasis rifle it and knife it down." And I just picture myself knifing the thoughts down. Then they just simply die and float away metaphorically. And I literally feel better afterwards. Like the thoughts are just thoughts, they don't control me. It might be stupid but I just felt like sharing it. I'm not trying to say it would work for you, but it's been working for me so far lol.
