Seer/Empath need help

I've grown up with the abilities of feeling loved ones even from mass distances away. Was hell when wife was pregnant and I'd feel her hunger and pains at work. I've always known when something was near and in the moments they were happening when a loved one was near or at death's door but last night I couldn't sleep, felt like bugs crawling on me causing me to itch and took 3 hours to fall asleep. I woke up to a call from my mother that my sister died last night while at work. My sister lived 600 miles away and was a heavy drug user. I wonder if the itching and inability to sleep last night wasn't her struggle and I guess after the autopsy we will findout if drugs were involved. My ask for help is, is there anyway to control these "gifts" I have to where I can control it more? What should I do?
