Many people here are complete failures (including me), I hope you don't feel alone.
NOBODY is a FAILURE, It's my opinion, in my 62+ yrs and an over the road trucker I've met all kinds of people. 100% of the people I've met had their own story. Some are limited by education, some by physical limitations, and some by emotional limitations, and then there's some with all the above and then there's those with PTSD due to, family, friends, war, and crime.
What they all had in common is they all tried to deal with their situations with the knowledge and abilities they had and without further knowledge they can't take it any further.
Most of those who feel like "failures" are those that "compare" their lives to others or try to meet other people's standards.
I tell them if they compared their lives to their standard and what they want, not other's, where do they stand, in life you are responsible for you so, take risk, be with the one you want too be with, work at the career you want, same goes for , school, trade, food etc.....
Now some people will feel like me. Living in pain, physical and emotional, and terminal illness, we've been to all the doctor's and been told there's nothing more we can do. I personally want to die with dignity and on my terms.
When I choose to die I believe Jesus Christ will be by my side giving me comfort.
The Bible tells us to trust in God and when it's our time to die God will be with us and comfort us. I believe wether we die of natural causes, a car accident, murder victim, illness or suicide it's on God's timing some time the way we die God uses it to educate, or get a message across to our love ones.
Sorry this is so long. And of course this is my opinion.
