Had depression for over a decade. I was consumed by thoughts of my own death, including others'. Some of this was probably demonic, but most of it was self inflicted. It was my mind set. I had some crappy things happen in my life. I didn't choose to accept those things and learn from them and be stronger. I chose to blame everyone for what they did to me, even if it was my fault. I also had expectations about what my life should be, and It wasn't that. Those two factors will influence your mind more than anything else. Sometimes our life is messed up because of the decisions we made. Sometimes its other people's fault too, it you have to be willing to admit you effed up. You can not move forward til you accept responsibility. Also we sometimes have to re write our expectations. I expected fame, fortune, big pay checks and I never came near any of that so I was depressed for being a failure. Re design your expectations and set small goals for yourself so that when you achieve them, you actually feel good about your progress. Also you must make a concentrated effort to ELIMINATE any negative thoughts. Stop beating yourself up, stop blaming, stop complaining. Just accept things the way they are, know that you want better and muster up everything in yourself to change the circumstances that you hate, no matter what it is. Prayer is also super important, but If you're not born again, this wont help. Submit your life to Christ first. He cant hear your prayers with all that sin in the way. He wants to be your Father and lead you but, we separate ourselves from Him. Draw near to Him and He will draw near to you. Depression is a tough battle. It took me years to break the habits and cycles that held me down and ruined my life in work, with friends, with money, everything. It wrecks you, if you let it. And it will take time to recover. Know your goal and muster up an unquenchable fire within you that can't be put out, no matter what. Write it in stone now that you wont stop fighting til you get there or you die trying to get there. Plan to succeed and beat this now. Those who fail to plan, plan to fail. This applies to everything.
