Crohn's is a very individual condition, no two patients are the same and as such there are very different approaches to its treatment. Its pretty common to start people off on a steroid to bring the flare up under control and settle the symptoms down. I am currently on a different steroid called prednisolone which I'm in the process of weaning off.
Steroids are great drugs for bringing down inflammation and can make most people feel dramatically better within a short space of time, but they are not perfect and have a lot of side effects and risks. Prednisolone is the worse of those commonly used for Crohn's, it can have all sorts of effects including thinning the bones and creating steroid dependence. Entocort generally has far less side effects, but it is still a steroid and isn't meant to be used indefinitely . Due to this, it's common for people to be placed onto a medication such as an immuno-suppressant which aims to control the disease long term. The most common ones are Azathioprine, 6MP and methotrexate. These drugs do have potential side effects and you need regular blood tests to check your liver and kidney function, but they are generally much safer to use long term and have good success rates. The next step after these are biologics such as humira and remicade which work by targeting specific parts of the immune system and blocking their action, these drugs are usually used in severe Crohn's or in cases where the disease doesn't respond well enough to other treatments.
It's common to feel alone with this illness, it's very hard for people who don't have the condition to really understand how it makes us feel. You aren't alone though, there are lots of people here who can relate to what you are going through and how you are feeling and there's almost always someone around that has had a similar experience. While we cannot promise to always have the answers, we can at least share our own experiences and offer you our support.
I don't live in the US, so I don't know much about the support available there, but the
Crohns and Colitis Foundation of America has lots of information and should be able to point you in the right direction.
Edited to add - don't be overwhelmed by the lists of medications some of us have in our signitures, some doctors prefer a combined approach or some of us have had reactions to some medications and have had to try an alternative path. There are also a number of members who have multiple conditions and therefore need a wider range of medications to control the various aspects of our illness.
