There are many things that need to be done in combination. What is daunting for you is that change that is too big can be frightening and upsetting. Think "small adjustments."
The psychological fact is small changes are much better. When you take very small changes those can be long lasting and easy to apply. Most human beings are just trying to make it in the world.
These are small micro habits. Small changes. Some people claim about how good their lives with their "internet facade life", but most of us are just working on being happy. It takes more work to be happy than it does to be sad. It is easy to be sad. It is not about just being "happy" or "staying positive" it is about balance of the positive and negative.
The pursuing, or chase of material things only make matters worse. We should be pursuing happiness, and working on surviving, and most struggle with just that idea alone.
Getting out of bed is a struggle for them. Life is a struggle for some. Pursue "happy" and nothing else. Most are chasing the "house" the "car" the "material item." We forget the most important thing of just basic happiness. Good luck and remember small adjustments are easier.
