Hi Ky, congratulations on the upcoming wedding! That's definately time for celebration. Planning a wedding is extremely stressful & you also are the middle of school, thinking about graduate school & dealing with health problems. Managing all that & keeping yourself positive is a huge task but, from your email it sounds like if anyone can do it you can. But, the key is going to be taking things one at a time & asking for help - delegating. You cannot do this alone. Finding a balance is key - you may not be able to do everything but, do the things that bring meaning & happiness to your life for your future.
It will get better & you will get better. But, you'll have to find the balance for you with your health. Those things that help to make you feel better more of the time. The right doctors, the right support which could include cognitive therapy & especially the right physical treatments such as water therapy/yoga etc., and taking time to breathe & get well.
As far as graduate school - it's becoming more & more important in the workplace these days. But, it really depends on your field. Staying in school may give you more time to get better versus having to go out into the workplace now. But, it's a hard decision. I know that the company I work for that a masters degree is highly prized & helps a person to get the leg up initially. But, the bottom line is that just having a degree doesn't always cut it. It will get you in the door but, it's what you do once you are in the door that counts - certainly knowledge is power but, it's how you use that knowledge - bottom line. And as a note most people that I know that didn't get the masters after the BA do wish they'd done it as it's much harder later on to go back while working full time. Also keep in mind there are many fields though that you can do into that are more flexible with hours & if you "consult" or work from home you set your hours.
Trying to stay positive is key to you getting better. Know that you are not alone and that you will get better. One day at a time. Believe, have faith & remember to breathe.
