How can one deal with severe depression, despair, and intrusive thoughts, and return to closeness with Allah after neglecting acts of worship, given the lack of family support for Ruqyah Sharia and distrust in psychiatrists?

We ask Allah the Almighty to heal you and relieve your distress. We advise you to mend your relationship with Allah by engaging in good deeds, benefiting people, and staying away from sins. For if Allah is pleased with you, He will rectify all your affairs. Maintain your prayers and remembrances. The best cure for waswas (obsessive whispering) is to completely disregard it. Ruqyah (exorcism/spiritual healing) is prescribed for the afflicted and others, and it is permissible for a Muslim to perform ruqyah on themselves. We advise you to consult with psychological experts.
