I think a big problem is that for most of us what we equate with “healthy” isn’t the same as our body’s interpretation, so I would say to go with your body. If your body is telling you it’s better off- by making you fertile again- then listen to it, everything else is just superficial.
easy to say, I know. I do sympathise with you, but we are all on a long process and it’s good that you’ve seen the improvement of getting your period back, so just stick with it and I bet you’ll see many more improvements which eventually will please you more than your old body and clothes.
I have just come round to this way of thinking, and have stashed away my previous clothes so if I need them one day they will be there, but for now there’s no distractions undermining my progress at the moment.
Good luck xx
