I am debating to get a restraining order against my ex, am I overreacting?

[Stardust]

My ex broke up with me almost two months ago after a year long relationship. For a while the two of us tried to be friends and talked once in awhile. I told him last week that I was happy now and that I enjoyed being single. He responded by saying he wanted no further contact and sent me a long message prior saying he still loved me even though he was with someone new who he had been with less than a week after we broke up. Today I got on my myspace and I received a long diatribe about how he wants to be friends now and he can't sleep at night and has to take nyquil. I blocked him off my myspace and changed my profile. I am starting to become fearful, even though he hasn't called the house or shown up at the front door. Yet. I live with my family and I am hesitant to be home alone during the day. I am also concerned for my mother, who deals with severe depression. Right now I am unemployed so I am home 24/7 mostly. I did not respond to the message he left me, but I am starting to consider a restraining order if he continues to attempt to contact me. Luckily, I have changed my myspace, aim, and e-mail/yahoo info. I am also considering finding out how to block a caller on our home phone, even though my parents and sibling know not to pick up the phone if it is him calling cause we have caller id. Originally I was sympathetic to how he was feeling, but now its starting to get creepy and stalker like, especially considering that my myspace account was set on private and he somehow found a way around that. Its having an extremely negative effect on my psyche, to the point where today I cannot eat lunch because I am sick with fear and worry. I deal with depression and anxiety, and I cannot go near the town he lives in. My original gut reaction is to wait and see if he shows up in person at my house or starts calling excessively, because I am not sure a judge would grant a restraining order unless there was examples of obsessive behavior. Am I overreacting at this point, or should I begin considering a restraining order?
