How to make Shaitaan leave me alone and not attack me all the time?

I have heard that shaitan was afraid of Umar Ibn-e-Khattab (May Allah be pleased with him). Since after Ramadan, Shaitan is not leaving me alone. He is constantly attacking me by means of doubts in my heart, derailing my focus, causing me depression and anxiety and hopelessness, and putting me in a disconnected and lost, despaired state. I really want to get rid of Shaitan the rejected. Is it possible that he stays away from me and leave me alone, with Allah's help inshaAllah?
