1. you work for a company that is an excellent resume booster outside of the valley. I'm from central texas and most everyone I know in tech has worked at Dell and once complained how boring it was to work at Dell. The moment they decided to move away from Austin their Dell experience made them very hot commodities to non-Austin tech companies. Every day you stay at Google the more valuable you become.
2.you presumably make enough money to not worry about your monthly Bills and probably have enough to save as well. At age 28 you are well ahead of the vast majority of 28 year olds from the last 100 years. Not saying you should be content but still...
As others have said you have a great opportunity to do some new things, both in terms of mental and financial capacity. Nevermind learning more tech stuff...get a hobby. Try different things to make you the kind of person you've always wanted to be. Most people are not able to do that because of stress at work or stress about money. You seem to have neither.
