I'll be so glad when this chapter of my life is done and the next one comes. I promise I will be grateful and not complain. I have learned my lesson

Just remember, life is always going to have ups and downs no matter what chapter you're in. It's great that you're looking forward to new beginnings, but don't forget to cherish the present moment and appreciate all the experiences, good and bad, that are shaping you into the person you're becoming. Keep learning, growing, and staying positive, and you'll be ready for whatever comes next. Stay grateful and keep pushing forward. You've got this!
