So on top of the other great suggestions here, I can share a trick that has helped me to get me past periods where I was feeling either depressed or stuck or anxious or otherwise not my best. If I have a decision to make ("Should I go for this new job?" "Should I move to a new city?") I ask myself, "What would the happy, confident version of me do?" and then I do that. When I'm depressed or fearful I tend to make bad choices that perpetuate that state; when I'm happy I tend to make better choices that make me happier. This is a way of short circuiting that feedback loop and making even a small step to feel better.
