When we are going through depression, one of the most adverse effects is a complete loss of motivation and energy, a state that inhibits your capacity to tackle the problem. Eating the right food is crucial, and while people with depression sometimes find like they don't want to eat at all, it's crucial like they make the effort. Rather than eating "comfort food," which is rarely comforting for us afterwards - getting some fresh fruit and veg, as well as carbohydrates from non-overly process foods like pasta or potatoes can help. Research 'healthy cheap recipes' on Google or Reddit and find the balance between healthy and delicious.
Drinking plenty of fluid is essential for your mental health. Ideally, five or more glasses of water a day protect you from being dehydrated and depriving the body and mind of the power that is extremely vital. Water adds oxygen into our body and brain, which helps with headaches, lack of focus, tiredness or even food cravings. A balance between proper hydration, non-processed foods and consistent sleep (even it it's late), will have an immense impact on your life, guaranteed.
