Did I Just Experience A Psychic Attack?

Is this called psychic attacks, or psychic anxiety? Lately I been feeling like my gifts are disappearing, but it always turns out this is not always the case. Yesterday was a confusing day for me as I experienced a sudden event. I was outside feeding the dog, and suddenly, I began feeling hopeless, wanting to give up on life, and started crying. I made the decision to quit college, and just say forget it all. I even contacted my college to withdraw from courses and cancelling orientation. I decided to take a nap afterwards and woke up with the change of thought. I contacted the college, and they were able to reverse the whole process which allowed me to enroll back into my courses. This isn't the first happening, but only incident that alerted me. There was another incident where I was sitting in my room and started having suicidal thoughts. It's just this range of emotion that comes upon you so suddenly. I suffer from PTSD and brushed these occurrences off as part of the illness. I was just speaking with someone about college and expressing my excitement about the Fall semester approaching just the day before. As soon as I touched the water hose, I immediately became overwhelmed with this sudden emotion. Of wanting to cause harm to myself, and completely give up on life. I was feeling ugly, and a total complete failure. There is this woman who stay in the house that constantly harass me, abuse me, and all the time constantly bully me. My abilities transformed into dreams in which I receive messages, and premonitions still. Imagine being in a classroom receiving your education all over again and ending up graduating. I am naturally gifted, but yesterday scared me. I never experienced a sudden feeling like this. I even wrote an email to someone detailing how much of a failure I am, how ugly I am, and how this woman won over my life. I was even stating this evil woman won over my life, and college just wasn't right for me. I even mentioned that she was right about me being stupid, and dumb. I would like to also mention that she wasn't home at the time this incident occurred. I fell asleep and woke up feeling totally different. Before going outside, I was feeling okay, and happy feeling. This changed instantly when I was outside giving the dog water. I never felt this kind of range of emotion overcoming me with guilt, and total hopelessness about life. I even started crying in the house feeling like a nothing person. Yesterday was the first time something hit me this hard and I noticed it. I can't believe the email I sent someone detailing how I am a nothing person and calling myself ugly. I was extremely happy about this semester starting and transformed into this kind of emotion.
