Ideas to stop thumb-picking?

I don't know what to do, my hands have become so numb and bruised because of constant washing hands, i have started hating each and every furniture around me, beacuse i feel they are not clean although they are being cleaned regularly but i cannot stop these thoughts. I clean my phone, bluetooth, charger with wet wipes each day, i don't touch any object around me, i am not being able to focus on my studies or anything else because of my ocd ihave stopped going out, everyone around me is so fed up of me. I have consulted so many therapists and been taking ayurvedic supplements too but nothing works. It is getting worse and worse, please if anybody can suggest me how to overcome these thoughts!

I need advice. I’m constantly washing my hands after going to the bathroom/touching something I find gross, but it doesn’t stop at just washing. I have to keep washing til I feel right (usually 3-4 times). It also isn’t just my hands, I go all the way up my forearms. I know in my head that once is enough. But I can’t kick this repetitive behavior. I know I should just start only washing it once but I don’t know if I can handle the panic that will come after. I need advice/tips if anyone’s gone through something similar what worked for you. Im just sick of this

I’m having a big OCD relapse and would like to hear anyone’s tips on how to be present and healthily deal with these intrusive thoughts and the “need” to preform compulsions. Thank you!!
