WIY – I hear what you are saying but I think that this can be said about any day of the week if someone chooses to sit in solitude and contemplate their lives.
Of course, however every other day of the week is full of distractions that keeps you from dwelling on this. Shabbos comes and there is no escape, which is why I feel these thoughts are more prevalent then.
TAOM – He’s making it so hard cuz if you weren’t challenged you wouldn’t get anywhere or use all your potential. Ever read A Thinking Jewish Teenager’s Guide to Life? If not I strongly recommend it. It is one of those books that has been sitting in my room for years and probably has never seen a bookshelf cuz I’m forever re-reading it when things are down. (Shopping – it’s right next to Beyond a Reasonable Doubt 😉 – another one of my favorites) TAOM, you’ll get through this as well. Yknow some beautiful things don’t start off looking beautiful. However in hindsight, you will see how all this pain fits in to the master plan and how much it has helped you become who you are. You know this already, but keep repeating it to yourself. And just stay strong!
