I've been in the same boat. It's really, really tough, and even though it doesn't seem like it's even possible, it does get better.<p>Many things have already been said here, one I haven't seen is (basic!) Mindfulness - no psychotherapists or other psychos involved. Just self-paced, listen to a 5-min mp3 once or twice a day. This one: <a href="https://www.amazon.co.uk/Mindfulness-practical-guide-finding-frantic/dp/074995308X" rel="nofollow">https://www.amazon.co.uk/Mindfulness-practical-guide-finding...</a> comes with a good free app (book is OK, but written by a professional, so not airy-fairy).<p>Unlike my vegan childless friends, I don't have the time to go on retreats or walk barefoot on moist grass, but I do have 5 mins to breathe in peace, in work breaks for instance. I'm not sold on Mindfulness as a cure for everything from obesity to cancer, but it sure helped me gain a new perspective on life.<p>The basic premise is, our minds have an autopilot of thought tape. These thoughts tend to gravitate to negative, angry, protective thoughts and emotions. It's not that hard to break that loop though. This "stream of consciousness" is not objective, but rather a very biased resampling of our experiences. With minimal training, you can recognise it and refocus it.<p>For example, I used to often fume about work annoyances on my way home from work, thinking about e-mails I received, or what I'd respond next time, etc. With some Mindfulness under my belt, I can just switch it off. Look out the window of the bus and <i>genuinely</i> enjoy not changing nappies <i>right now</i>. Or when that infuriating guy from sales sends you another e-mail, and your brain serves you the many angry memories of past interactions, recognise that, separate the memories from the e-mail that really just needs an "ok, I'll look into it" response, and you can get on with your life.<p>It doesn't make the world an easier place for you, but it helps you focus on the good bits that are already there. As a new parent, you probably don't have the time (or sufficient sleep) to pick up a new hobby, but 5 mins most days is feasible. And, chances are, you might discover there are nice moments in the day, when your mind isn't flooding you with memories of the bad stuff.<p>That, and also: when we had 1 child, my wife and I tried to look after them together, always. We now figured having some "you time", as others say, is invaluable. 2 hrs of looking after a child on your own, plus 2 hrs of time to yourself, is a huge difference. Just sit and chill and watch Netflix if that's your thing. Or do the weight lifting / running / skydiving in that time. Did wonders for me.
