I'm not a big fan of negative situations myself. I do my best to avoid them or to handle them as efficiently as possible. One thing I never do is subject myself to negative energy on a regular basis. At least I TRY to never do that. Sometimes even the best effort to stay positive doesn't succeed.
The best thing to do in regards to a class like the one you're talking about is to stick with it. It'll be over in another month, anyway. Just keep yourself motivated and remember that this is all so you can get whatever degree you're shooting for. That degree must be pretty important if you're spending the time and money for the education.
So, just say a prayer before you go in to class each day and when you leave, spend a few minutes getting rid of the negative energy you've just absorbed. The best way to get rid of negative energy is as follows:
WATER WATER WATER WATER WATER! Grab an 8 ounce glass of water and say a quick blessing over it. Here's a blessing suggestion: "May the Lord bless this water so that as it passes through my body, it takes all of the negative energy with it and leaves me refreshed and joyful again."
Of course, with every blessing, it takes faith to make it work. As I'm always saying, meditation and prayer is the best way to bolster your faith. And of course, spread the love around!
I'll be praying for you.
Love and Prayers, Shay
