I am living in the past. I am afraid of the future?

You need to stay positive and not look to try and fix your situation with quick fix solutions or self destroying methods. You need to find something that you like to do and take your mind off of your ex. Keep positive things will get better. You need to know what has been going wrong and learn from it. It is hard. No one sad it would be easy. What do you do with your life. Do you work, exercise, eat healthy, socialise and any hobbies. If you don't have much of a social life then I would try meetup.com. It is good for people who are lost and need something more in there life. You can meet new people and enjoy social activities and events. It can be intimidating at first but give it a go you never know what you might find. If this does not work then you might want to try meditation, yoga or mindfulness. Just google it and see what you find. If this does not work then you need to find someone to talk to like a psycologist. Just remember there are options and it is a trial and error. It may or may not work for you. Just pick and choose what works for you. Try also keeping a diary of your thoughts, routines and daily life as this will help yourself and others to see what is going wrong and what can be done to help you. When you have thoughts or behaviours what have you done to try to fix this in a positive way. If someone offers you drugs either prescription or illegal do not use them as they don't help you deal with your issues and can make your situation much worse. Hope this helps you.
