Could be worth signing on with a good agency who takes the time to get to know you and your strengths, so they can present you properly to recruiters? I quite often receive applications from candidates who have had a break in their career history for family carer reasons (it's by no means always childcare, it's often parents or partners who've been unwell). It doesn't put me off interviewing them, as long as their skills and experience before the career break are good.

If you are available to work now, it could be worth trying to get some temping/voluntary experience implementing the learning from the courses you have completed, so you can also demonstrate you can put the skills into practice. Good luck.
