Why am I so irritated all the time

Why am I so irritated all the time! Im getting back in my word again and having more of the Lord back in my life. I get so down in the dumps that I just sabotage myself, bacause i know that’s bad, i know it’s not of Jesus. I get so fustrated I cry because of it, and i think it will never end. I know It wont be forever, but i having faith that God can easily take it away from me. Me being irritated makes me not want to serve the Lord, and bitter, and hurt oTherS. What can I DO? Is there something wrong with me? Am i not doing enough?? Im born again and saved if that helps
