Stuffing, hiding, and/or discounting our emotions is probably part of the reason why some of us are on SI.
I understand the guilt Neznayou. You don't feel you have the right to feel anything. But you do. Emotions are real. They are valid.
You must learn to feel those emotions, and then also effectively and clearly convey those emotions to those around you.
Example: QS says we're going to dinner at 6:00pm on Thursday night. However, at 2:00pm, I receive a text that says, "Sorry. Have to work late. I'll make it up to you." I would understandably be very hurt. However, 2 months go by and he has yet to make up our dinner date. I start feeling anger and resentment. What do I do with it?
1. I can stuff my feelings. I'm cranky, hurt, and feel undervalued. When he says, "What's wrong Aubrie?" I'll snap back, "Nothing QS. Nothing at all." He'll say, "I can tell something is bothering you." I pop off with, "Don't worry about it. It's nothing." But it is something. And I just lied to him about my feelings. I stuffed it deep inside. And it's going to fester and infect. Next thing you know, I'm yelling at him, the kids, the cat, the mailman. I'm a ball of anger, hate, and resentment. All because I stuffed.
2. I set aside 20 minutes to say, "QS, remember when we were supposed to have dinner and you cancelled for work? That really hurt me. It made me feel your job was more important than spending time with me. Remember how you said you would make it up to me? Honey, it's been 2 months and we have not had dinner together yet. I feel hurt by that. I feel unimportant to you." What he does with that information is completely up to him. He may get a clue and arrange an evening together. Or he may stay oblivious and head off to another work project. The point is, I opened up, I was honest, I shared my feelings. I was authentic.
It takes practice and time. But you can do it Neznayou.
