My best friend moved away

I have been crying every night for weeks without a break. It got to a point where even looking at her name hurt. I told her that because I wanted to be honest. Her react was just to be offended. I really need to learn to shut my mouth. I used to tell myself that if she ever moved I would kill myself. Ngl I’ve thought about it many times. I just don’t know how much longer I can take this.
