I would recommend hermetics and alchemy.
Its more of a belief system in my opinion. A way to be "self-aware" so to speak. However it doesn't force you into choosing a label or a god.
I'd start with 2 books. The first one is really short and light, but the principals inside are key to understanding if you want to function properly in a world ruled by subtle energies.
You can get the book on amazon or read it for free here.

The second book is a lesson in using transpersonal alchemy in everyday life. However, the seven steps of alchemy are incredibly comprehensive and have many parallels with other paradigms which help you understand what each step represents. Therefore, this book is a bit longer, but well worth it.

I personally seem to sum up my understanding of magick with those two. The best way to compliment that knowledge is to have a good understanding of how modern science and technology looks at the world and the picture it sees. Ignoring reality is definitely not the right answer. However you will come to find the parallels between the modern picture and ancient wisdom. Use this as a tool to understand the subtle energies even more. A good place to start would be quantum mechanics, modern psychology (Archetypes and Collective Consciousness), and math (chaos theory, fibonacci sequence, fractals). These are all modern studies of the boundaries of reality, we would be fools to ignore them when working with magick.
I personally don't take any stock in complex rituals or altars, however the best time to do your work is when your mental capacity is full and you're focus is maxed out. You want to be "in the zone" so to speak. This is one of the biggest reasons most beginning magicians are attracted to chaos and sigil magick is because it works and its very simple. However, as you approach more and more complex understandings of the subtle energies you will have to look to other paradigms for specific answers. These understandings usually come in the form of intense spiritual experiences and you will know what you are looking for. The more intense the spiritual experience, the more "altered" state of consciousness you tend to be in. These are induced most healthily through meditation, but some experiences will take years of practice. Some people seem to have a natural talent for it. Shamans eat entheogens.
Have a goal, pick something you wish to understand more about and as the big picture falls into place you find yourself aligning with the energies that support you and your goals, however remember that its a relationship of sorts between you and the subtle energies (god, spirits, ect). Therefore, as you well know with your family, fighting solves nothing.
As you begin to align with these energies and you start to realize your full potential I highly recommend you practice sigil magick. It will humble you and as your knowledge grows you will start to understand why its working. Once you see this you're pretty well set to perform magick without the sigil. The key to this is understanding how one pattern is really just a piece of the giant pattern.
While some people do chants and cast spells for money. I simply keep mine on the proper channel of energies and watch it grow.
However, once you come to this understanding you realize that the amount of money you have is pretty well related to your person's current value and that may cause you to do something else.
Whatever it is, its not waving wands around and building altars. Its simply living with the knowledge and being.
Sigils are always fun, but change in this world comes from action and most magick in my opinion is knowing the right actions to take to get results.
I still practice sigils, but its more or less become one thats evolved over time.
EDIT:
PS: If you want to study more of the occult and the ancient mysteries a lesson in myth, what it is, how it comes about, the purpose it serves, ect, is necessary. In that case I recommend reading some Joseph Campbell. I highly recommend "The Power of Myth", or "Hero with a Thousand Faces".
On top of that a great place to start studying the ancients is the Manly P Hall's "Secret Teachings of All Ages", which is easy to read, but really acts like an encyclopedia on the mysteries.
