Yes its worth it, I was in a similar stituation 5 years ago and then I got my apprenticeship and haven't looked back

In the new year company's and training centres will start looking for new apprentices. Until then deicide what trade you want to do.
Try the ECTIB they will pay for you to go to college for a year, pay for digs, travelling and £50 per week. During that time you will do all you City and Guilds level 3 work, key skills and other courses eg first aider, rigging and slinging, cheery picker, fork lift, welding coding etc. And find you a company who will take you onto their books as soon as you've finished (usually large engineering company's).
Then you do 2-3 years full time site work to build your NVQ level 3 log books then your done and earning double what you are now (triple with overtime)
Then its up to your company/yourself if you want to go to college and do your HNC and then UNI or like myself am going chargehand then foreman route hopefully manager one day.
