With anything mental health, it's always important to take things one step at a time and set goals along the way, no matter how small and "insignificant" those goals may seem. When you work toward a goal, you have motivation; then when you achieve that goal, you have a sense of accomplishment. But the trick is to create small, achievable goals. For example, maybe you're heavily depressed and don't even want to get out of bed. Well, maybe start off by setting a goal to brush your teeth and another one to take a shower. They don't have to be big, daunting things like "clean the whole house."

The idea is this: if you have motivation and you're able to achieve things, you start to feel good about yourself.

With anxiety in particular, sometimes you have to face your fears in order to get over them. I'm not saying you should ALWAYS do this, but for example, if you're afraid of making new friends in real life and you're too anxious to leave your house, well, you will never make new friends. But if you push through your fear and put yourself out there, there is a chance that you *will* make friends. Not a guarantee -- because nothing in life is a guarantee -- but you will never make friends if you hide away in your house and refuse to come out or refuse to invite people over.
