Why can't I seem to get past the words they told me, even years later?

Probably because those words are targeted at your insecurities, and it seems like other people are affirming what you thought was wrong with you or your bad qualities. Remind yourself that they only say these things to be hurtful, and that they don't reflect who you really are.

because they are stuck in your mind and they are very hurtful but you need to know that you are better then anything they told you because they were probably jealous and so they tried to put you down

Because words are really painful and they can stay with you for the longest time. The words that others say can stick with us for the longest time and we tend to always reflect on them and they always pop back into our minds regardless of the time that has passed since it was first said. It also makes it worst when we over analyse what was said and constantly revise it thinking that it might some how help but it usually has the opposite effect.

While "they" may have put ideas into words, the fact is that you have adopted these ideas about yourself or your situation. Words that have no relationship to one's own perceptions of reality are quickly forgotten. Of course, words from people we love and trust have a greater chance of being believed. Ultimately, however, we are the ones who choose which words stick with us and which words we let go of.

Because when you've been bullied for a long time it becomes all you know, and it sticks in your head. You've just got to break through your past and live in the present.

Words hurt. They scar for so long. What is important is to realize how far you've come since you first heard the words. You're a better person. A stronger person.

Because whether we like it or not it impacted us and left a mark by someone who was important for us

We hold onto things that we do not want to accept or to let go. Our brain is very interesting and remembers little details that once created an emotion inside.

I can understand your feeling.Be positive and move on.Past is past.Thinking about that will hurt you.

Some words tend to leave a lasting impression when we have a certain emotional response. If words hurt us or lift us up strongly, we tend to remember them.
