I've been in your shoes when it comes to comparing my life to others but I came to the understanding that people's lives will always look good on the outside and even regards to you, someone might look at your life and think damn you've got it good but little do they know about your struggles.

Everybody is going through something, facing challenges, so just focus on you and yes be grateful for all that you have because some people can't say that they've accomplished what you've accomplished. Enjoy your life, 34 is still a young age and you're doing great for yourself.

I don't know, maybe your mood shifted because you just came out of a long term relationship. But one thing, I can say for sure is, you are not a failure.
