Allah is Great and you will be fine.
My advise is as follows:
1. Kindly consult your GP for professional and medical advise on this. It’s very important you do this as soon as possible. Allah has blessed the professionals with wisdom for them to be able to reach out to those in need.
2. Try as much as you to ignore the doubts either after wudhu or salat. One wudhu or salat is enough in this regard
3. Try as much as you can not to miss reading and reflecting on verses of the Quran daily
4. Don’t forget Sadaqa to those indeed from time to Time
Allah will make it easy for you
