It's SO hard. People snap my hand off to work for them now, when I applied after my mat leave no-one gave a shit. I'm the same person, had most of the same skills. I think I've applied for my current employer about 5 times in the past with no interview. You just have to keep going, keep motivated, hard as it is.
I think I put career break or something like that, but what got me the job was application after application. Eventually I got a really crappy 2 days a week fixed contract but 4 years later I'm full time (by choice) in a senior role and earning £10k more. Sometimes you have to take something unpopular to get a foot in the door again.
Like any sort of person facing discrimination, you have to be 10x better than the equivalent person, so get some good advice on your applications and interviews. I signed on which was actually a good experience, some supportive people, second pair of eyes for CV and discipline to apply for a lot of jobs.
Reskill too, anything IT based, even your regular office applications, they've changed a lot in recent years and now teams, sharepoint etc are all commonly used.
Good luck, keep going.
