Struggling with intense doubts and OCD in worship

Assalamu alaikum, I'm a sister who has been dealing with really difficult waswas for almost two years. Whenever I think I'm improving, it suddenly gets worse or a new worry appears. All my doubts revolve around salah, wudu, and ghusl. It began with Surah Al-Fatiha-I kept repeating the verses over and over until they felt correct. I would redo my prayers because I thought I missed a verse, a rak'ah, forgot to say Allahu Akbar at the start, or made the wrong intention. It got so severe that one prayer could take me 40 minutes. Then it moved to wudu. I kept thinking I missed parts or didn't wash a limb properly, spending ages in the bathroom. Even after finishing, I'd go back and do it again from doubt. At the same time, I'd feel like I passed wind-just a sensation-during wudu, while maintaining it, and in salah. It was an endless cycle. The anxiety around prayer and wudu is overwhelming. I constantly tighten my stomach to prevent anything from coming out, which only causes pain and more false sensations. I got married seven months ago, and my husband is incredibly supportive, alhamdulillah. He helps me with wudu, stops me from repeating prayers, and tries to pray most of them with me. But for the past few months, I've had severe doubts about sensations in my private area, making me think I need ghusl. Ghusl is already stressful, so my OCD latched onto this as a new torment. I can't live normally. Any movement-sitting, walking, lying down, driving-triggers thoughts that it resembles an orgasm and requires ghusl. I keep checking for discharge, which only makes it worse. I've done countless ghusls because of this, and stopping feels impossible. I even stress during istinja before wudu, wiping repeatedly to ensure no urine or discharge remains. This has shattered my mental health. I struggle every day and can't find peace. It affects my husband too; he constantly reassures me, and it's taking a toll on him. Soon I'll have to pray two salahs alone while he's at work, and the thought fills me with anxiety. I want to heal for myself and for him. Please, any advice?
