I have so many thoughts after reading your post. I'll try to keep this short. Bottom line, yes you have the right to be angry and to let the feelings out. It is healthy for you to do so. It also sounds like you were pushed way past a reasonable limit.

On the other hand....

My husband yells and swerts and crashed things around when he is angry. I hate it. I feel frightened that he will break something important to me or expensive to replace. I also have a tendency to take my emotions from other people. Him being so angry makes me anxious. Meanwhile, after he rants and raves for a few minutes he is alright. I am still upset. Maybe your family feels a little the same.

I often feel anger. I try to keep a lid on my emotions and let things pass. Occasionally I will say something in an angry way or act in a way other people think is rude. I always get in trouble for it. People act like I am not allowed to get angry and it make me furious. I see other people yelling, being mean, bullying and acting childish and nothing happens to them. Why do I have to be so perfect? So, I totally understand how you are feeling. If I find and answer I'll let you know. I hope you will do the same.
