Some thoughts, not gospel...
As others have said, it's the breathing out that counts. I re-learnt how to breathe (used to be able to swim a bit when I was a teenager) when I was on a 3 week holiday where I had access to a pool every day. I thought, this is crazy, I'm fit & strong, but getting out of breath swimming less than 50m. It must be technique. So I concentrated on my breathing and by the end of 3 weeks was doing 800m.
I found that breathing every third stroke suited me best. So firstly, find a pool where you're not going to bump into other people; i.e. pretty empty. That way you can keep your head down without worrying. Secondly, wear goggles unless you're really, really comfy with eyes open underwater - again, it's to allow you to relax more.
First stroke, breathe out, second stroke, breathe out more, third stroke, twist head (try not to lift it) behind arm and breathe in. Try and establish a rhythm, don't worry about speed, just concentrate on getting the breathing synchronised. Once that's done, you can keep going for ages and then you can think more about swimming technique.
Not lifting the head when you breathe; i.e. just twisting, is quite difficult. I manage it better on one side than the other. My dad, still swimming 1k 3 times a week at 93, still does it much better than I can (although finally I can swim further and faster than him if I try
). Watch someone with good style to see what it looks like.
You may find breathing every 2, or every 4, better for you, but once you've sorted one out, changing to the others is pretty easy really.
Finally, get some lessons. If I was going to start swimming regularly, then I would get lessons, simply to sort out my stroke technique. If you watch a really good swimmer, it's quite incredible (and frustrating),, how they seem to go so much faster, with slower strokes and less effort. Most of that will simply be down to technique.
