Where does self-compassion come into it for you,
@Bartek? I sense that you're being pretty hard on yourself. Your TMS brains LOVES pressure and judgement - they are great distractors. My therapist has said that Pressure leads to Judgement which leads to Repression which leads to Symptoms.
She gave me a quick little tool to stop the obsessive cycle of pressure and negative thoughts. Awareness that you're obsessing (aka Ruminating) is the first step, so hooray for that, right? When you become aware of obsessive negative thoughts and fears, literally say STOP to yourself. Stop and breathe a couple of times. Then ask yourself (writing this down would be even better, you just need a scrap of paper) What do you WANT?
This forces your brain to step out of the squirrel cage of "ack, stop this, I don't want this, this sucks, I'm never going to get better, what if this keeps going should I go see a specialist what if they find something what if I can't ever run or cycle again what if what if what if aaaaaaaaaargh!"
Instead, you stop, breathe, and come up with a short positive or constructive answer to the question. This not only breaks the obsessive negative rumination, but allows your brain to visualize, even briefly, a different outcome. Visualization is a surprisingly powerful self-healing technique. "I want to go take a run without worrying about whether I'm damaging my (whatever body part). "I want to go biking and have faith that I'm perfectly safe even if I feel a symptom" "I want to go out and f***ing enjoy myself for once!"
This is a brief exercise, but your TMS brain will resist it and provide all kinds of excuses to avoid it. Believe me, I know what I'm talking about!
Mind you, if you want to take this thought and keep writing, by all means do so! Perhaps just writing down what you WANT will trigger strong emotions around why you're not getting what you want. So even though this starts out as a brief positive exercise, you can take it any direction you want if it leads to examining your deeper emotions. Do you remember the free-writing exercises from the SEP? The experts say that this kind of writing is not about "keeping a journal" because you should not keep it. Simply scribble stuff down as it comes out of your brain, without editing or fixing it, without regard for syntax or spelling or even legibility, and afterwards dispose of it. Dr Hanscom calls it expressive writing, Nicole Sachs has created the term JournalSpeak, and I just call it writing shit down. Nicole even has recommendations for using a computer instead of pen/paper (

Good luck!
