There have been many proposals that have come for me, but none have gone through for their own separate reasons. Are there any duas specifically for marriage, one that can help with the process of looking for a spouse? Are there also any duas to help with mental health, as I fear that my mental health will continue to deteriorate throughout this process of looking.

1. Recite this verse many times a day (25:74)

2. Do this prayer if you can and ask you hajaat
3. Seek professional help for mental wellbeing. There is nothing wrong with that and it will help you a lot, such as CBT.
4. Write down why the proposals are failing and work out a plan with the family
