How to Protect Your Heart and Peace with Islamophobic Racist Parents?

Assalamu Alaikum everyone, I’ve been a Muslim for a few years now, but my parents still don’t know. I was too scared to tell them before, and honestly, looking back, I know that fear was justified. You see, they’re islamophobic and racist-though they don’t show it on the surface. I always admired them and based all my choices on wanting their approval. But when I was going through deep depression, they never tried to understand what I was going through or support me. Maybe that’s just how I see it. Sometimes I feel like hugging them (we’re a very reserved family, always have been), but then I remember the hurtful things they’ve said and done. I know I’d end up being the one to feel guilty again, still in pain, without ever getting an apology. We live together, and I can’t move out right now. It’s so tough. Just showing them the basic respect and keeping minimal conversations-out of duty as their child-makes me feel guilty. What can I do day by day to guard my heart and my sanity? How do I stop their words and actions from crushing the little mental peace I have left? I don’t want to slip back into severe depression. Honestly, please don’t give me advice like “Have sabr and tawakkul,” “Talk to a friend,” or “Go to therapy.” I’ve been patient and try to rely on Allah, but I only have one or two friends and I can’t keep burdening them with the same problems. And therapy? I’ve tried it many times with different therapists. Have you been through something similar, or do you know someone who has? Can you share practical tips? Maybe something like “Trick your brain using this method whenever you feel sad or angry.”
