Well do you have any interesting people in your life now?Is there any way for you to immerse yourself with a new group of people and new activities to distract you from the past?Or if you are missing the particular things you did with those people can you try them out anew with someone new?If a past event is kind of haunting you can you write a long letter(which you will never send)stating what happened and how you wish it could be worked out?Sometimes putting something down on paper takes it out of your immediate thoughts giving you a chance to move on.Maybe try this method of pushing your memories out and making room for new experiences,write it out.

i understand that. my past tends to creep up on me in the most unlikely of times, especially when im alone. It was like i was haunted. What help me was to do things that made me happy. Like watching a disney movie or something funny. or doing a physical activity. Keeping your mind busy is a good distraction, and always counting the small things that your grateful for. If that doesnt satisfy you, you have go out there and make new memories :) i know how scary that can be but once you do it, it feels good. Just Try.
We have to somehow not forget but learn and understand from our past. Understand that this is how i felt and i felt obligated to feel that way, they shouldnt have treated me that way. Its okay to feel the way you do.
And trying to see it from the other persons perspective, because those people who arent in your life, were once in your life for a reason. sometimes things leave in order for new things to come in, better things :)
And learn from it to make your life better. Now you know what kind of people you want in your life and what people you dont want. And heres quote for you to help with the bitterness

"the best revenge of all: Happiness. Nothing drives people crazier then seeing someone have a good fcking life"

so be happy, have fun and live in the moment!
I hope you feel better and this helps a bit!! xoxo lucille

A very good book helped me with my obsessing. The book is, Stop Obsessing by Edna B. Foa. It is the only thing that ever helped me. I still use the techniques regularly.

I can relate to what you are going through and I'm sorry. It's mental torture. It took me years to live in the present but sometimes I still have my moments. Writing things down helped me. "Don't let the regret of yesterday and fear of tomorrow be the thieves that robb you of your happiness today." I don't know if I got that quote right but I wrote it down and have it by my desk and read it everyday. Working on your self worth takes time but in the end you should know that you are someone special and in control of your own happiness.

I wish I knew!! I spend too much time ruminating over past relatiionships and people I will never see again as well. Same here with the wishing things had been different wishing I hadn't screwed up.

If I figure out how to stop thinking about them constantly I'll pass the info along to you.

Hugs I know it is really hard and emotionally draining.

I get what you are going through. I too obsessively ruminate about past relationships and it hurts like hell. All we can do is accept that what has happened is in the past and try to move on. Easier said than done I know.

I think lucillegem has got it right: we just have to get out there and make new memories, which is what I'm trying to do. Distraction techniques don't really do it for me. I need fresh, fond memories to push the bad ones further to the back of my conciousness.

is it possible you have OCD? ever look into it? it's something that I've battled with and found good coping mechanisms. if you wanna find out about it, you can private msg me and I'll tell you about it.

Hi, I'm in a similar situation, except for me it's only one person. I write a lot of letters. Crazy, overemotional, erratic letters that in the end I know I won't send but it sure feels good to get stuff out. Its also really helped me make peace with a few things as well.

My opinion is you wont forget your past friends until you make new ones who can possibly take their place in your life,

another book I heard about but haven;t read is

Drop the rock

not sure who wrote it....prob a priest....
