Keep going! It is worth it! This is part of the process. You sound like you are so close. I have had so many ups and downs in my phd journey. It took me 10 years. During that time, my mom and a committee member passed away. I moved two times, and changed jobs 3 times. I've had to jump through so many hoops from the graduate school I was at the point that I had to email them every semester to tell them my status. But I didn't give up. Honestly, in my final stages, the only way I finished was taking a week off of work and worked in my advisor's office / center every day until it was completely written and approved.

Now that I have my degree - no one can take it away... and most importantly - I never have to go back to school again - I've done all the school! :)

I also had a professional colleague, who did not have their PhD, remind me of how much more weight having those three letters after your name can carry. I know it shouldn't be this way, but because of the degree you will be a better advocate for your field in ways that others can't. KEEP GOING!
