After 5 or 6 months of suffering, I decided, at some certain point, that I need to do something about it and that I need to get over it and not waste my life. I started small, step by step, waking up, taking shower, going out for a walk, etc. I used to WFH, but I reversed the habit and started to go to work place everyday.
Then, I got a gym membership and started exercising almost everyday (after so many years of physical inactivity. I am 25 BTW). I started cooking and eating healthy. I take multivitamins everyday with an additional dose of Vitamine D and Magnesium. I eat only vegetables (lots of them), rice, chicken and fish and sometimes beef steaks. I also take fruits everyday (usually Oranges, Bananas and Apples). I also drink Coffee (one cup in the morning and sometimes another in the evening) and Tea with Ginger.
I feel much better. Now, I have a routine, I am more active and I get some work done. However, I still suffer from a slight lack of motivation and happiness. I still feel a bit unhappy and I am not as motivated as I was before the whole depression thing hit me. I don't know why and I have no idea how to solve this part to become the super motivated, super focused and super productive person I used to be.
