Why do I keep feeling bad when I face things which I thought I was over them ?

It takes time to get over things, it is a process that cannot be rushed. Allow yourself to feel whatever you need to feel, and know that it's quite okay.

Sometimes we get "triggered" in the present by things that remind us in some way of things that happened in the past. While this can be disturbing, it is also fairly typical. I feel like one of the keys to dealing with this effectively is to practice mindfulness. If you think you have been triggered by a past event, try consciously remind yourself that it was a past event, you have moved on, and that you are better. And remember to breathe! In through the nose, out through the mouth through pursed lips.

Because you have a conscience and more than likely you are not over the problem. The better question ask is how can i help with overcoming this feeling

Some learn to forgive, but never ever forget. Allow yourself to be upset but don't let it control or define you. Understand that those were dark events and move forward. You don't have to be happy about what happened, all you need to do is accept it.

Getting over something is not equal to stop having feelings. You can be over a situation or person, yet still hurt when you are forced to face them. Pain is a strong emotion, and you can't be hard on yourself when you feel it over a situation. Be patient, and take things slowly, and remember that everything is temporary, even feeling badly.

Your unconsciousness is telling you that you're not fully over it yet. You need more time, and maybe help, to allow yourself to get over it.

Well, you can feel bad because you really didn't end up letting go of them. Which is pretty important to the process.

As time goes on, the pain of something bad lessens, but when we are faced with something that triggers a memory of the bad thing, it makes it hard to get over it completely, especially if people keep bringing it up often.

You haven't made peace with the past. Understand that lagging on the past will make you miss out on the present, which only happens once.

Because of the memories, you might be over it but memories always come back and try to haunt you. But you have to remember you got over them already
