If someone makes dua to Allah asking for the tears they shed to be the thing that stands between them and hell, Ie, that their tears are a means of attaining the mercy of Allah and thus being saved from Hell, is this a form of shirk? I said this dua and now I am worried it as a form of shirk?

Ustadh AbdulAziz al-Haqqan
If you suffer from Waswas, you should go to a psychiatrist.
