My hubby is also a complete worrier we joke that he's not happy unless he's worried about something, the plus side of this is that he is also a perfectionist and that anything he does is always planned to perfection and always goes of without a hitch - because he's always so worried about things going wrong!!

Dont beat yourself up about worrying about things will mean that things will (hopefully) never go wrong !!

Try to occupy youself as much as poss, maybe planning new routines and outfits, trying to come up that new idea that hasnt been done before !!!

Bio oil or Almond oil are both good for stretch marks, from personal experience use almond oil, cant comment on bio oil as never used it but heard its good.

Take care & hope to see you out and about soon
