Assalamualaikum - Struggling with constant sadness, need guidance as a Muslim

Assalam u Alaikum, I'm from India. My depression began during the COVID lockdown when I was young. My parents and siblings used to argue a lot, and that made me feel overwhelmed. As a result I developed CPTSD (I still have it) and later I had religious OCD about committing shirk. I managed to overcome the OCD in early 2025 (it started in early 2022) - OCD felt like hell for me. I never told my family what I was going through because of their constant fights and arguments. My father can be very toxic - some days he's fine, other days he's in a very bad mood. While I had OCD I planned to run away from the house for a long time because he would hit me or abuse me with words whenever he got the chance, and it affected my academics. One day after an exam I actually ran away, but then I worried my mother would be worried so I came back that night. I never told them why I ran away, though some friends found out. Now I fear and feel guilty about what they think of me and I overthink a lot about it. I don't even attend that institute anymore since it was my final exam. First it was the OCD making me overthink, and now this guilt and constant worrying. Please help me - how do I move past this? My childhood was chaotic and it's still affecting me. I feel like I can't see a therapist because family members might mock me or call me mentally ill on different occasions. JazakAllah khair for any advice. I would appreciate tips that fit an Islamic perspective - supplications, community resources, or practical steps I can take while being mindful of my family's reactions.
