I've decided that I give up.
Could you expand on what you've given up on?
Everything. I have no motivation to do anything right now.
It can be difficult to be motivated at times, but it shouldn't be your default setting. Loss of motivation and drive is a sign of depression and I encourage you to reach out to a counselor or mental health professional.
Okay.
Giving up isn't good and you deserve better than that feeling. Reach out to someone who can help you work through the lack of care you are experiencing.
