Why can't I live the moment when I am supposed to, and things keep coming to my mind in my happiest moments?

it is often difficult to block out negative thoughts if they are triggered by certain events or locations. some choose to live in their past instead of moving on, rehashing what if scenarios in an attempt to see if their past troubles could have been changed by something out of their hands.

You think too much.You are also aware that it's going to happen and you are afraid of ruining your moments.

This happens to me a lot as well. I find telling someone I care about,what I'm thinking helps a lot.

You're problem may be biological. You should consider talking to someone you trust about your options, such as seeing a professional who can help.

Because it's just yourself doubting things and reminding yourself of the past. But the past doesn't exist and it shouldn't matter.

You're thinking too much into the future and you're making yourself want to enjoy that moment. Don't think too much into the future or force yourself to enjoy a moment. Instead, don't do either. Just live it without thinking or making. Let it come to you, naturally.

I think it's because until someone has realized the past is in the past and it's over, they can't truly let it go. Therefore, it continues to haunt them. Which is natural. The way to solve this, most of the time what we need, is to get closure. Once we have truly understood what and why a certain thing has happened in the past and processed it, I think it becomes easier to let go.

You're haunted by your past. Correct me if I'm wrong, but it's possible that you won't allow yourself to be happy anymore after your experience. When your happy you're reminded of every reason why you shouldn't be, but that's not true. Just because something bad happened in the past, doesn't mean you need to keep reliving it. It's hard to get over things, I know, but we at 7 cups can help you to the best of our abilities to get over whatever's troubling you.

Sometimes our brains do crazy things, learning how to deal with the things that come to the front of your head is the first step to recovery, once you've done that you'll be able to bypass the thought and be able to live in the moment, sometimes this can take a while but you will be able to learn techniques that you can use to help you such as focusing on mindfulness, taking a few moments out of your day to really focus on the good things, and separate them from the bad. Once you've done that you will find it easy to do so in day to day life

I used to struggle with this issue often. My mind was constantly working. I would be out on the town with my husband on a gorgeous evening yet unable to stop my mind from replaying confrontations I had with my dad earlier in the week or practicing my next move when confronted with a new issue. It took a lot of cognitive behavioral techniques, meditation and journaling but eventually I retrained my mind to settle down and now I enjoy many wonderful events completely in the moment and it feels great! Be patient though because this took me over 2 years to reach my optimum level of mental peace.
