Hi there, maybe you have too many things going on in your life, I know this forgetfulness I am having is most likely from that in my case my pdoc says, and maybe my meds.
Don't feel like a loser, you aren't, you are "human", no need to be compelled to "punish" yourself.
I've done some really odd things this year, too many to list, one was a certain cleaning solution for my contacts I grabbed instead of the saline solution and put it on my lense to rinse off and ouch, I realized what I did, but don't you think I knew to rinse with the saline and instead grabbed the same stuff and put it in my eye to rinse, had to get to hospital cause even rinsing after with the right stuff didn't stop the reaction sooooooooo I went to the ER and had to spend an hour there while having my eye flushed out.
Now I put red tape on every new bottle of the cleaner to allow myself to see it is the nasty stuff, the bottles of the saline and the cleaner are the same size and almost look identical, the eye doc said that was clever of me to now do this and even said he is going to advise his patients that use the same stuff to try "flagging" their cleaner solution bottles.
Sorry, got off track here, but please don't be so hard on yourself, sometimes we do things wrong even if we have been doing them for years right.
Please take care, and know it was a good idea to stop by before doing something that may harm you.
There are lots of warm, supportive people here that can help you through the "low" or "exasperated" times.

Sincerely,
DE
