Just because you can’t provide a lavish lifestyle doesn’t mean you can’t be an even better father and husband then you were before. Give them your attention and time and love and wisdom and that will go much further than anything that money could have bought. Control what you can from this day forward. Doesn’t take money to be a better version of yourself. Stay positive! Life is too short to consume yourself with worry and regret. Things WILL get better if you move on with positivity, gratefulness for what you have (health, family, etc) and optimism.
