It's heart breaking for me to read this posts.
Just remember most people don't have wifes and kids, and majority don't have 500k or a business.
And sorry to say this but if u feel there is no help for you, there is no help.
But do it for your kids. Don't ruin their future. They are kids so if u need to act happy u will act happy, it's much better if they understand it later as adults, ruining kids emotions at early years is the worst thing that u can do.
I've been there brother i always helped and cared for everyone but always they would makeme feel bad because they felt normal when i was there for them. I always tried to keep everyone in my family happy i was the one cheering them all and in response i got hits so low i don't want to talk about. My father was narcistic abuser who abused me all childhood, my mim supported him, i was alone all my life. Because of abuse i stutter and couldn't even speak in highschool. I couldn't say my name. But i never surrendered. I found the love of my life we moved to live together, worked hard but for 10 years we coudn't have kids. I was devasted, i tried to kill myself seveeal times but god did not want me dead. I gambled everything i had because i wanted to be most miserable man alive. I gambled it all on purpose. I continued gambling and abusing drugs for years. Went to a point I was so depressed i have no words to describe. My suicide attempt with 100g speed eated awaken me, when i woke up in hospital my wife was with me and she begged me to promise i wont do this again and we will succeed. There are 1000 reasons i won't say why i got to this level but this was a turnover where i stopped feeling sorry for myself and put my wife's life first. I acted for years im happy. I wasn't. But then GOD gave us a kid. Doctors said my wife could never had kid. But we got it. That changed everything. Now i live for my kid and the people who care for me and my fanily, im nice to everyone who needs it and thats all but the most fun part is i don't pretend anymore im really a happy person. I survived trough hell hell hell and nothing destoyed me only left scars which made me stronger and proud of myself to a point i can't even believe who i am now in character and psychology . I even learned to speak so i don't stutter anymore. I gave my best besides the pain which was unbearable. I was a robot for years. It all passed and all emotional and psychological pain and agony wen't away. I beated it all. You can do it too. Life is not easy. Life is not beeing happy all time. It's ying yang. And yes i gamble stll but only play tournaments for fun and competitiveness, and have the character to never spin a single bet solo, if not tournament.
Hope this inspires you, just do your best for your family and god will show u the way and give u the strength. And remember to ask the universe if you need its help. It will help will give u the energy to get through anything i promise
