Take a break from it for a while. When you get impatient you get frustrated and stressed which is bad. After a few days or a week, then you can get back into it, it takes time. Start with MILD like others said, go for DILDs for now. Maybe write RC on your hand to remind you. You can do it, but you have to be patient. Try mantras and autosuggestion at first. Write in a dream journal for your recall.
Best of luck.
