Is it normal that i believe january 23 is cursed after what has happened?

January is a terrible month for me. Most of the deaths I have experienced have happened in this month. January 23 is the worst day of the entire year. This is because my grandmother, who I was very close to, died on this day in 2012. She was 88 and suffered from Parkinson's disease. It was the worst day of my life so far. It will be 8 years next year, but I'm still not over it. On this day in 2013, my pet fish died after I had had him for about 7 years. I had plenty of time to get attached. I found it rather shocking. This year on January 23, I found out the second worst news of my life so far. My best friend had disappeared from my life a few months earlier and I found out that he was dating my therapist's daughter. He didn't bother to talk to me for 10 months. My therapist told me that they had started dating in August of the previous year. I can't approve of this because I have no other friends and I want as much of his time as humanly and physically possible. I was depressed and it showed for a month. I had to get a new therapist because my therapist would not give me any more information about my best friend. Sometime next month, they will have been together for a year and now August hurts. Most of the bad things that happen to me are on January 23! I fear this day of the year now more then ever. is it normal that there has been a string of bad things happening to me on this day and is it normal that I observe and fear it?
