It does not necessarily sound like what you seek is an end to life but perhaps a resolve. Perhaps no one has been willing to listen to your pain, or perhaps aiding you in finding a resolve has proven impossible.

I eventually decides that the "purpose" that I desired most out of my life is impossible. There is no other purpose that I desire in its place, no matter how grand or how simple. For that matter, anything can prove demotivating without a purpose to follow. However, I decided to give another frame of thought a chance-- nothing could motivate me towards a bland, ordinary life, so instead, I choose to live without purpose but still for the sake of curiosity. While I am here, I may as well explore this world to its fullest until I do move on.

Essentially, one could stake their life on a series of goals that they wish to achieve. But if one lacks to motivation towards achieving those goals, then they may never reach them regardless of whether or not they openly decide to quit. If one lives for the enjoyment of the present (and work for savings to maintain health in the current and future), then there is far less stress in the long-run. Everyone talks about "success" being the only way to life, but in the end, success is relative. Only the individual can decide what he or she defines as success in his or her own life. No one has the right to define that success for someone else.

The only time that you should force yourself to suffer is if it comes down to your simple ability to survive. Beyond providing for food on your table and a roof over your head, every other decision is a choice or responsibility of option. In the end, earning a wage for an apartment for one is quite simple. Adding others to that family is a choice made by the individual as they see beneficial.
