To think that it isn't insane to have a 'just in case' bag?

Yep, I have one too - sanitary products, paracetamol, mints, tissues, mini deodorant, dental floss face powder, lip balm and a comb are in mine.

I have all that sort of stuff separately in each bag, but it makes way more sense to have everything in one bag.
I used to travel a lot with work and my going away bag had a compete set of toiletries, make up and a phone charger to save to the trouble of remembering to pack everything.

seems very sensible to me.

Sounds like standard issue handbag territory. What's your husband got to do with it. Non issue

It's a great idea. As someone who has had anxiety, having those backups keeps your mind from worrying about illogical things. Odds are you won't need them, but if you do, you're prepared.

I have more of a prepper style 'just in case' bag (and I'm not generally a prepper, it's just the one bag!) but it came in super handy the other day when my entire town (and two around it) lost power for an hour. I had camping lanterns plus a windup radio, which great as the power cut was so bad that mobile towers were down too, so it was the only way to check the world was still going! It doesn't have loads in it - some over the counter medicine I regularly take, a spare pair of glasses, a solar charger, a power bank.

I think I will add some other basics too it now.

This makes perfect sense to me. I have a pencil case with my 'essentials' in - paracetamol, strip of regular meds, sanitary products, hand gel etc. I just move it between work bag and everyday day bag along with my keys and purse. In the car I have a small holdall with a wash bag and change of clothes, torch, blanket and power bank. I travel 1hr to office over the moors and on more than one occasion have been able to get to work but not home again when snow hits!

I’m type one diabetic wearing an insulin pump so I leave the house with a number of things related to this. We also live on a narrow boat. Important documents are in a bag that is easily grabbable just in case!
some people have bug out bags for other types of emergencies if you are a serious prepper. We are not quite there yet. I have a house handbag - it contains diabetes stuff, chargers and pens. It’s an old Radley bag that looks like something Miss Marple would use. Then stuff transferred to outdoor bag when leaving the house.

Omg, you should meet my DH. He has a rucksack with various pockets and pouches. He has everything from a puncture repair kit, duct tape, and zip ties to hair bands, lip balm and plasters. I never have to carry anything.

I even have spare deodorant in my car after forgetting to apply it once.

I always have one. Plus a hospital bag packed

My small one has
Painkillers, nail file, lip balm, hand cream, tiny multi tool, plasters, tampons, mini pack of wipes, deo, mini perfume and some other bits I can't remember

Hospital bag
Pjs, clean top, socks, underwear, flip flops, charger bank, charger lead, headphones, book, spare medication, then stuff like a mini shower gel, deo, wipes, cleanser, ear plugs

I have a little zipper makeup bag with essentials in it I move between bags.

It's got makeup, meds, work lanyard, tweezers lip balm, spare pen loads more stuff

I was actually thinking of making up a bag of clothes, toiletries etc as the PP mentioned (who had to evacuate their home without notice). This doesn't seem to be what you're taking about OP, but as the climate emergency worsens I think it's a good idea.
I also have my medication kit which I carry around everywhere.

You might want to add another £ to that emergency bus fare!

I do similar - very handy and I'm never without this bag I might need.

What's in it?

I'm the same and I have one too. Men don't seem to get it though, my DH certainly doesn't.

Absolutely nothing wrong with this OP
I have one too, a makeup bag... I keep wipes, lip balm, mini sewing kit ( you wouldn't believe how often I've/ others have used that) hand gel, paracetamol.

Lots of women I know have very similar too.

I have a wallet that contains tampons, towels, lip balm, hand sanitizer, pain relief and Imodium if that's what you mean? I don't use a bag very often so it's not always with me, but always with me at work, or if it's a longer day out and I have got a bag with me (be it mine or DH saddling the family back pack!)

Is that not just a handbag?

Unless you have a full first aid kit, a machete, 80 toilet roll and 2 weeks worth of rations, carrying a few essentials is perfectly normal.

I personally have a habit of taking emergency herbal tea with me because I’m fussy about herbal tea. I went into hospital for 5 days for a major operation and I took like an entire tea farm with me. 😂

Nothing wrong with this at all. I have a ziplock bag containing a box of lemon teabags, a pack of tissues, a £2 coin (emergency bus fare) and a black pen. It lives at the bottom of my laptop bag so it comes with me automatically on the days I have to go into the office.

I do this and so does my husband. We're both autistic , but it makes great sense to us. We're never without a phone charger , basic meds , lip balm , hand cream etc.

Not weird at all op.

I have two of these - one for essentials like lip balm, tissues, paracetamol, hand sanitiser etc., and one for makeup. I move them between different bags for daily use. Totally normal imo.

I have a packed bag in my closet incase I need to grab a flight short notice lol. You're fine!

A phone charging thing I’d understand but being anxious about not having lip balm is not something I get. I do like to have a lip balm but it’s hardly emergency stuff. Mind you, I have an allergy that triggers my asthma and I regularly risk it and go out without my inhaler. It’s so rarely an issue.

It sounds absolutely fine and quite normal? I always have a hospital bag packed, which sounds really weird to people, but I have chronic illnesses and never know when I’m going to end up there in an emergency and it just reassures me knowing there’s one less thing to worry about. Just do whatever you need to do! X
