Stay positive. A year from today, you will look back and be grateful you did not give up. Life will be so much better, and so much of what worries you now will no longer matter.
What is important is not so much how long you live as whether you live a meaningful life. This doesn’t mean accumulating money and fame, but being of service to your fellow human beings. It means helping others if you can, but even if you can’t do that, at least not harming them.
There's something called Grace. When it locates you, it doesn't inspect your certificates or your background. It simply changes the story of your life. I pray the Lord's Grace locates everyone.
