You can get over this....!!!! You must find the strength inside of you to push and push. It hurts to think of life without that person.... Your stomach in knots, its hard to eat, sleepless nights, and the most awful feeling of gut wrenching loneliness. I once lost the one I thought was to be my wife. She was everything I knew. When she ended it, I was lost, confused, hurt, and turned all that anger and hurt towards myself, also indulging in drugs and alcohol. You have to see that life is beautiful, and remember the days before she walked into your world. Unfortunately, she has made up her mind. All you can do is move on with your life, even if things could end up working out for you both and you do get back together. it will not be anytime soon. You need to get your life on track even if its taking it day by day, minute by minute.... try to get out for some fun for atleast an hour each day... even if your thinking about her just for that hour dont talk about her...!!! slowly build back your self reliance. I was in your boat friend and everyone gets through their problems their own way and at their own speed.... but it does get better... i thought id never love again, but with some time and positive attitude and keeping my mind busy, i moved on and found a wonderful woman that i am so in love with and our relationship is so great, i feel like an idiot waisting so much time pining over the ex....!!! YOU WILL OVERCOME THIS BUDDY, YOU GOTTA BE STRONG AND FORCE YOURSELF TO STEP OUT OF THAT BUBBLE FOR A LITTLE WHILE EACH DAY..... God bless you man I hope you see the beauty in living your life.... because being happy will make you feel 20x better than any drug!!! good luck bro, find your path!!!
