This is important to see. It sounds like you gave them more value then they actually deserved. You are still doing that without realizing it. You are still holding onto your own hurt feelings that were caused by two people who never had the capacity to respect your feelings in the first place.

Do you understand what an emotional vampire is? An emotional vampire is someone who constantly needs others to vent their emotional challenges to, they are not emotionally mature where they can resolve their emotional challenges on their own. This type of person is NOT going to appreciate you the way you think, in fact if you don't service THEIR need the way THEY want, you can most definitely expect that person to trash you and tell the world how awful you are.

It's often a person that chases this need to be "special" to make up for not feeling that way when they were a child. OR its a person who was treated like they were special who expects that same treatment from others as they tend to feel entitled. Both need their ego to take priority and neither will give you "genuine love". You know that saying "sheet floats"? Well, that's typically what gets to the top sadly.

If you have not moved on then there is something you need to learn from the experience you had with these two people. Part of your healing is recognizing your own part in this bad experience. From what you shared it sounds like you gave more of yourself than you should have to individuals that did not have the ability to appreciate you. If you are only wonderful when you are constantly servicing another's emotional needs then that's a red flag.
