I haven’t read your story but I surmise from the other posters that you are a caregiver. Caregivers are at an increased risk of depression and suicide because they feel like everything is on them and they don’t take the time to care for themselves.
When you hear the pre-recorded segment on an airplane about what to do in an emergency, they always say if you are traveling with children to put your own oxygen mask on first and only then to help the children put theirs’ on. Caregivers are no good if they give it all in one big spurt and it kills them. You need to be in it for the long haul so you have to make time to energize yourself.
If the baby is healthy, you could put it in a stroller and go out for an evening walk, jog, or run. It would give mom a break, you and baby time together, and get you some exercise and adrenaline. You could also go to the pool, though it is getting too cold for that. Our neighborhood pool is full of dads with kids in the warm evenings. If your wife is the one you are caring for, also try to have a “date night” with her if possible. Watching a movie, taking a rose-petalled bath together, giving her a candlelit massage, reading books you like aloud, dancing if she is able, watching the stars, discussing the news, or any other activity which re-focuses your relationship to husband and wife instead of caregiver and charge will help re-energize you.
Don’t fall prey to instant gratification like pornography, mindlessly watching the tv or surfing the internet, gambling, drugs or alcohol. You’ll feel good for the moment but you’ll feel worse quickly because they will only drain you more.
Make time to grow physically and intellectually. For 15 minutes after you put the baby in bed, you can practice lectio divina. If you can’t do it at home, do it over your lunch break. Eat healthy food and drink lots of water, especially if your sleep is being disturbed.
Also, make sure you are praying your morning and evening prayers. If your wife is able to join you, say them together. It is just as important to refresh the soul as it is the body. You might think you don’t have time to add in prayers and reading and running every day. You have to make time for yourself otherwise you’ll just wear down and be no use to anyone.
Make a schedule. If you get up at 6 AM now and immediately go to care for another, get up at 5:55 and say your morning prayers, then go do the caregiving at 6:10 instead. If you are skipping breakfast because you are taking time to make it for someone else, make sure to make enough for two. If you don’t have enough time in the morning, go to bed 30 minutes earlier so you can calmly finish all the morning tasks without feeling rushed and neglecting yourself.
You can also hire local teens to help if you can afford it. I have a neighbor who works evenings so she makes up a menu and buys groceries, then pays the neighbor girl to make dinner 5 nights a week. There are ways to care for yourself when you are caring for others, but all of them require you making the time to do it.
