Yes. Most of what you describe are typical side effects of prednisone.
The low blood pressure, however, could be related to adrenal suppression since you have been taking the steroid for so long. This is a case that occurs sometimes when the steroid downregulates (suppresses) the adrenal gland and it is unable function normally, causing hypotension under stress.
I would recommend following up with your primary care physician to check if this could be the case.
