Pleeeease help me. 😭😭😭

Guys I'm going to get locked up for murder. Like I'm kidding but I'm not. My child has pushed me to the breaking point. I love him more than anything but these terrible twos are horrendous. NOTHING PHASES HIM. He is very strong willed, very independent, very head strong and stubborn. I don't believe in spanking but I've got him a few times because I couldn't take it and it did nothing. He got close in my face and screamed at me. He will NOT sit in timeout. Yes, ladies in the back saying, "You just have to be consistent! If he gets out, move him back!"...I am consistent. I've heard it all before. However, literally the moment my hands move off of him, he dives out. The m-o-m-e-n-t. I'd have to physically hold him down in timeout. Which of course, isn't effective. When he does go and he sits, he doesn't care. He dances and sings. Now I know you all are like..."Well if timeout doesn't work, do something else!" Ok like WHAT? That's my issue!! I've taken things away. He doesn't care. He's lost his favorite toy or the tablet for example for the rest of the night. He gets plenty of attention. Like I'm at a loss. The worst part?? I work in and have my degree in child development!! He's just a different breed. So so so so stubborn. Please help me. Any advice is appreciated.
