not me, but my mom who had cancer and most likely suffered with depression or something along that line as she often talked about wanting to take her life. this (possible) diagnosis was disclosed and i will never truly know, this is just a feeling. she was hiding it from us up until the point where she slowly started to lose the ability to walk (i will never forget this, i was in high school and was supposed to go to class but she called me, telling me she is at a hospital and that she can barely walk. i skipped that shitty class, i did not even think about it) and eventually my sister and i both knew. metastatic breast cancer.
she was taking therapy for a year. i would oftentimes sit next to her on our couch and hold her hand while she cried. she cried and cried, and prayed to god that she dies. at that point, my depression only getting worse and all i had to tell her that i love her and that i understand, and that i wish i could go with her.
i knew she was not going to get out of this. there were times where i would get up at 2-3 in the morning to see if she was still breathing.
perhaps this sounds strange, but in the end i am glad that she did not suffer for long. 8 years have gone by, i miss her dearly but she had endured too much in her life. i am the age i am now and if she had gone out the way i want to currently... i would understand. would it hurt immensely? absolutely. but i would understand.
it is strange. for years i was looking for an answer, wondering why she was hiding this from us but then i came to the conclusion that her and i were actually very similar. i would probably not utter a word and let it eat me.
i guess this is more of a perspective from someone who was on the other end of the stick.
