One shouldn’t consider wudu broken unless they smell something or hear something. What if someone “smells” something almost every time. It could be a tiny smell of something or they think “did I smell something”. Do they consider their wudu valid and continue with all upcoming prayers with this wudu

Ustadh AbdulAziz al-Haqqan

Obviously this is waswas and you should be looking for a Muslim trustworthy psychiatrist.
