I have bad days. As I write this I'm having one (#inspo). There are sometimes when things just don't feel right. Some days are better than others and then you can feel like you're back in a rut.
Figure out what is making you the most upset consistently.
Ex:
1. Is it the people/person you're around?
2. Your job?
3. Your body image or self-worth?
4. Your organization of the place you live and/or work?
Maybe you get upset over one, two, all, or none of those things I've mentioned. What's most important is realizing what the main route of the problem is.
Next, I want you to get out your journal or a notebook and write why you're upset. Anything that comes to mind and your dreams scenario for the ideal outcome. Then I want you to strive for that. I want you to make a plan or a to-do list to make it seem more manageable.
