Therapy, exercise, and medication can change the chemical endorphin to ease depression and make it bearable. Severe depression is best diagnosed in a clinical atmosphere such as a primary care doctor or psychologist. Someone with mild depression can look at their current lifestyle to make minor, even drastic changes. Lifestyle and your environment around you can bring hope for a clearer future. Change is always great, so any change for the better can only be a shift in the right direction.
Being able to simplify your life would be a major material change.
Uncluttering. Clearing out the clothes that you have not worn in 2 years, donating furniture to make more space in a room. Or a small start like throwing away those old magazines beside your bed all can help clear your mind. The quality of life can be worth more when living your best life. Life standards can become shadowed by what you have materially, which makes you lose track of your worth. How you see yourself is the most important thing. Monks live a simple life and just think how peaceful their lives are. Living off a bowl of rice can seem a bit much, but not having to comb your hair for the third time can simplify life a little.
Taking a break during your day can settle your heart and mind.
To be able to recharge your batteries can be more than just sleeping at night. In the morning, before your busy day starts, you can take a minute to yourself. Some people meditate, some people pray, but they each have a common denominator: peace and silence. Taking a short break can help your blood pressure also. A moment during the day when your heart can work less to pump and have less force on the arteries can lower blood pressure. So when your boss is piling paperwork or someone else's responsibilities on you. Take a minute to clear your mind and lower your blood pressure to shake off the negative thoughts and be grateful for the job you have.
This leads to changing your world view.
The negative thoughts that can take over your day could distract your outlook for the entire week. False happiness can be a deadly killer, just as depression can. Becoming a happy human can be a difficult roller coaster of emotions, but how the emotions are dealt with can be the real ace of happiness.
When negative thoughts and actions stick with someone, so can the ability to notice them, then deal with them in a healthy manner. This can bring a sense of happiness and gratitude. Control of the sadness and negative habits will help your goal of self-happiness. A pat on the back for completing your home cleanse will help you complete the process. A thank you note from the coworker after you finish the assignment they were buried under will help your glow be seen.
