Im really sorry you are feeling this way. Sometimes when we need support from the people in our lives, we have to ask for it. Like you are doing right now. Otherwise people dont know. Please dont suffer through this by yourself, let the people who care about you know how hard a day you are having. It would be ideal if people remembered what we need them to, or said the things we need to hear. I know with my dbf I have to take him by the hand and lead him. I used to get angry (and still do sometimes) but I realized that until Im willing to share my needs with him, I cant get angry with him for not just knowing. My feelings are my responsibility, if I deal with them on my own, thats my choice. BUT if he still doesnt get it, after Ive told him, then I can get mad!
If you are feeling this way, then you might have to be the one to take the first step, to get what you need. I imagine that knowing they forgot, they will feel terribly, and from seeing youor posts before I know that you wouldnt want that for your friends. So take that step, it will benefit all of you. ~~hugs~~
