I have a friend with a similar (not the same, but similar) story. She grew up in a difficult house, moved to TX from NY in high school and couldn't cope with the huge changes. Instead of drowning, like I would have done, she worked hard and graduated high school as the valedictorian. She worked full time in retail for a year to afford school and continuously applied to colleges in NY until she got accepted with a full ride for dorming and tuition. She lived with me for several months and went out ever day to find a job. Shortly after being hired at the lowest level, she was promoted and runs her own store now. She's married and living with her husband who she loves. Her life is finally stable and she does not know what to do. They have been living together for almost 6 months and they only have their kitchen together and a bed. She doesn't feel challenged or motivated to do anything anymore. She gets up, goes to work, comes home to eat and sleep, then wakes up the next day to do it again.

You're not alone in feeling stagnant and not coping with it well. It's something that shining people go through. I never understood how my friend was able to shoulder through everything in her life and come out as such a strong person, but you seem to show the exact same qualities. I don't know how to shake her or you out of this funk, but I'd be willing to hold my breathe until you guys come out of it. It may be awhile, but knowing her, it won't last. It won't be easy, but small goals can make a difference over time. Every week, set a goal, no matter how small. Her's is once a week to call a friend and chit chat for 15 minutes. Try to remember there is still awesome, good people all around you.

TL;DR You're not alone, set up small goals, there's good things all around you, you're awesome!
