Here's the thing: I seriously doubt you actually love your company or your job. Instead, you're comfortable.

You're not challenged and you're flagrantly underpaid in a great tech city. I would guess someone decent with your profile should make 2x what you're making. Think about that. Would you recommend such a job to a friend?

You need to move on. There are lots of companies as good or better as your current one, trust me. Take it one step at a time - start with updating your resume. Hopefully this will get you excited about the next steps.

When you give your notice it will be an amazing feeling. All your self-esteem will come rushing back. Good luck.
