Ever since November of 2006 I have been undergoing some serious spiritual changes. After leading a life of sin for quite some time I got down on my hands and knees and repented of my wrongdoings. Instantly, I felt the Holy Spirit enter my body. For awhile I was on a “spiritual high” but it gradually faded away and now I find myself in the middle of an existential crisis that comes and goes every other day. Some days I find myself believing in God 100% and other days I can’t seem to believe in His existence at all. As a result, I am becoming extremely stressed out to the point that my blood pressure and pulse are becoming very high. I feel like I am going to have a nervous breakdown and go completely insane. Can somebody please tell me what’s happening and if this will ever go away…I’m about ready to give up and give into my doubts. I feel like I am under a curse or something. Somebody please help!
