Opening the book…
Getting help is nothing to be ashamed of, just be sure to do a bit
of work yourself to relieve the load of your helpers. How to do that?
Prepare a minimal working example
that reproduces your issue which will give helpers the perfect
starting point for your problem. If you don't know how to prepare
such a minimal example (also called MWE), just follow the link above.
Once you get a bit experienced, you will be able to solve problems on your own. :-)
Prominent places to ask are LaTeX.org or TeX.Stackexchange.
There are places in many languages around the world, you might find a community
answering your question in your mother tongue.
Why is a minimal working example (MWE) important?
A document is set up of many many little commands, which makes it complex. It is a bit like a stew recipe with many ingredients and different techniques of cutting the vegetables and cooking the meat. If there is a problem with a document, the reason can be chased down to just one or two ingredients, helpers don't need to see the whole recipe, it is yours.
