Which duas are the best for when feeling overcome with anxiety and depression and what can I do to help deal with or rid of this constant low feeling associated with low self esteem?

Kindly consider the following:

1. Try to keep wudhu as much as you can
2. Make sure to recite few curses of the Qur’an daily. Any verse will do
3. Repeat “ laa hwala walaa quewata illaa billahil Azeem” as much as you can
4. Repeat “ HASBUNALLAHU WANI IMAL WAQEEL” as much as you can
5. Consult a medical practitioner or a counsellor for examination
