I am going slightly crazy..

Let's get straight to the point,, girls can you help aa,,..so I am as said above cause my good friend of like 4 good company years of seeing each other constantly as completely an utterly ditched me they sent me a normal message an then soon after completely every contact I ave w/ them they have blocked me in. I really am unsure of the reason an our mutual friend says that it's cause I tried to cut myself last time I was w/ them although I never do that an didn't then I was simply upset. Me an this guy every human that saw us together said we would make an awesome good match romantic couple an he was always suggesting I only now really believe that I am going crazy.
