She is supposed to be immortal but her willingness to die overrode her ability to resurrect upon death, effectively granting her wish, even though her motivation was unclear at the most. It is never exactly stated why she killed herself, besides, "Is it wrong to want to feel death, even though if one cannot experience it?" but it is implied that she killed herself out of the uncertainty of their situation, which caused her a lot of stress (leading to her developing anemia and to suffer from alopecia) and depression and, apparently, she might have done so [[BettertoDieThanbeKilled way of escaping capture]].
** In 20XXIII, we do eventually find out her reasons for suicide and it was because of all the hell and uncertainty. The entire diary entry was basically her suicide note

She fails at it nonetheless.She attempts it again when she think she's killed Reimu.In Chapter 62, she was apparently contemplating it. Later on, we have Chen, in chapter 60, attempting suicide drowning herself, that of which she gave no motives for and probably can't on the grounds that brain damage from said failed suicide attempt possibly rendered her unable to talk, however, it is known that she wanted her mom back and had given up on life, which would be as far as motives go. Two chapters later, she does seem to have her motives somewhat explained in her suicide note, the which Flandre finds.
** In 20XXI, we have Nitori attempting suicide by ramming herself into wall, the which could have broken her neck. She failed.
