whats the meaning in all of this?

Im 23 and im tired of fighting this battle. I can no longer fill my head with the idea that it will get better. Im struggling everyday fighting back the tears. I seeked helped taken meds and yet i still feel like im living in hell. I think i will be done soon or hope i have the strength to end it. I feel bad for the ones i leave behind but enough is enough. My heart just wasnt made for this world. Its terrible we are put through this mental agony. I feel for everybody out there dealing with demons.
