In your profile it says your new to magic. Totally new. So what's up with saying you've been practicing for almost a year now? Why not state that in your profile?
Besides, things like this do take time. Do not push yourself. Pace yourself. Many people on this site have been practicing for years and are still learning. There is always something new to learn.
Are you grounded before you cast a spell? Is your mind clear? Are your intentions clear? Are you focused?
Keep these things in mind if a spell does not work for you. Some people even caste circles. But you do not have to do that. You can try, maybe it will be a method that works for you.
