One of the first things you need to do is stop saying "patience is very hard for me" and stop believing that. You MUST speak, think, and believe positive things about yourself, regardless of whether those positive things are true or not yet true. With that, you must live those positive things, whether they are true yet or not. Fake it until you make it.
Every time you say something, good or bad, then it repeats, reiterates, and reinforces in reality in you. So do the opposite - patience is an extremely easy task or thing for you to do, be, exercise. Say that in 3s each time, a few or several times per day. Your Mind probably would rebel, but that's to be expected.
Satan and the Gods and Goddesses can speak to us in various ways which we understand. They might be in coincidences, e.g. seeing the number 666 somewhere apparently randomly, or intuition or thoughts implanted in our Mind, or feelings or gut feelings... Ways in which we understand and realise individually.
Satan can help us, but we should learn to stand on our own two feet and take care of ourselves.
You can speak with Satan immediately, being honest and polite and respectful. He can hear you. You should meditate on his Sigils, as well. Doing so speaks to the God part of our Mind, and it helps is to attain attributes of Satan, like with the Sigils of any of our Gods and Goddesses. It might take a short time or a little no time before we notice things, though, depending on how open or atrophied we are or are not.
