Struggling with Wudu Due to Mental Struggles

I'm having such a hard time with wudu that I end up in tears and keep pushing my prayers back. I feel like there's no one I can turn to for advice because if I told anyone in person, they'd probably think it sounds silly, but it's really weighing on me and my iman. My issue is when I start wudu by washing my right hand three times. My mind convinces me I messed up, didn't wash it properly, or that my wudu is invalid, so I have to start over-even though none of that is true. At first, it only happened once or twice, maybe I'd redo that hand like 9 times and then finish wudu fine. But over the last few months, it's gotten completely out of control, and I can't stop no matter how much I tell myself it's all in my head and I did the step right. Now I'm washing that same hand probably 90 times, just standing at the sink repeating it over and over, sometimes my hand even gets wrinkled. I know it sounds so ridiculous, but my brain won't let me move on until I feel I did it correctly. I'm crying from frustration because I'm aware it's not rational, and I wish I could just make wudu normally. I'm also so conscious of how much water is being wasted when I repeat this step, but I truly can't help it. Eventually, I started delaying my prayers until nighttime, combining all four I missed during the day, because the thought of doing wudu for each salah felt too overwhelming... I know it sounds pitiful, and I don't know what's wrong with me. The idea of missing a prayer hurts me deeply, but making wudu is such a painful process-I'm stuck at the sink for 20 to 40 minutes restarting. I've wondered if this could be OCD, since I've had similar tendencies my whole life, but it's only in the last couple of years that it's started disrupting my deen. Is it even worth seeking a diagnosis? I'm too embarrassed to share this with my family, and I doubt any treatment could fix me. I'm begging to know if anyone else goes through this and how they cope. I know my story might sound pathetic-I just need some advice.
