There will always be those days where you feel unmotivated, and depressed. Everyone goes through those days. But what you must remind yourself to do, is to pick yourself back up again. Try to stand up to get out of that "funk" you are in.
Remind yourself to be happy. Constantly going through the day trying to be happy will allow yourself to see that you have a good life, and that you are truly happy.
Remind yourself that you have better days ahead of you. You may have had a bad day today, but tomorrow will be better. Have a good night's sleep, and you will wake up in the morning, reminding yourself that today will be a great day.
Remind yourself to eat and drink healthy. A balanced meal in your life will show you how precious your life is, and you will be feeling fresh and new. Healthy eating habits will bring joy into you knowing that you are eating better for yourself and for your body.
Remind yourself that you have many loved ones around you. It doesn't matter how many people you have standing by your side. What matters the most is that you have some awesome people who have your back and willing to be there for you.
Remind yourself that no one else can make you happy but yourself. It takes strength and courage to tell yourself that you are not happy and you are depressed. But the first step to a happy lifestyle, is standing up to yourself. Accept yourself. Make change in your routines. Do things that will make you happy. The little things in your day will add up and it will take some time. It doesn't mean that you should give up on yourself, this just means that you are making a journey. You will make a journey to your happiness. Just give yourself some time, and give yourself some change to your life.
These are just some reminders I tell myself when I'm feeling down and depressed. Hopefully it helps you think about the choices you've made in your life, and how you can make yourself happy.
