good luck. I hate needles also, but maybe they would be able to help you connect with other services that can support you in stopping?
if you still really don't want to go to teh ER, you can make sure you clean out out (antibacterial washes without alcohol work well), then use a piece of surgical tape or butterfly tape to close the wound. Keep an eye on it. If it starts to ooze or swell, visit a doctor. Keep it dry and clean...
