Wow, there are a lot of hopeless people here.
I don’t what conception of a successful or happy life you guys have, but it’s important to know that the main purpose in life is to know, love and serve god. Material circumstances don’t matter, you can be poor, sick, lonely, that doesn’t change that god has loved you from the moment he created the idea of you. And he still loves you the same. Christ has conquered death and paid the toll of sin, he has sent his disciples, established a church and the sacraments. The only thing that we have to do is to know and love him with all of our heart and do his will.
Since we are still affected from original sin, we won’t be able to do that perfectly. But this still doesn’t matter as long as you’re not giving up. When you fall, you have to get up again. Christ will welcome us every single time. Be it one time or ten thousand times. Doesn’t matter, because he is most merciful.

Guys don’t give up. You can turn your life around at every moment. Receive god’s grace. If life isn’t pretty, so what. Heaven has to be conquered. Every obstacle in life is a gift from god to be reminded of him and for us to practice virtue and refine our souls. So praise god for everything.

I leave you gentlemen to it. May god bless you.
