My brother, and now I have nothing

So me and my bro are pretty tight He lives with his newly fiance He told me that they were expecting a baby And told me to keep it a secret And I was the only person that knew He kept pressuring me to keep it a secret And I never told anyone Even though it was hard to lie to my parents

Well a couple days ago I tell my bro that I pierced my ear and my parents didnt know about It and I told him to keep it secret Like I was going to tell them I pierced it But when I was ready to tell them And he was critisising me like always

So this morning my brother tells my mom That he is expecting And he also decides to share my Secret along with it And he was concerend That I was hanging with the wrong crowd And im not acting like me

(well I hang with a good crowd And im acting the same Although he lived with me his whole Life he never tried to get to know me He just thinks he knows)

I wasnt just pissed at him but I was Depressed kinda (I was having a bad day already)

So we got in this fight Like dont you think its messd up

I kept this huge secret about a baby for 2 weeks And told no one about it And then I tell him one simple secret And he goes blabbing to my mom about it Hes 19 I thought he grew out of that

I guess not

I cried for like a hour Cus like I said im close to my brother Hes the only one I can talk to in my family But I realized that I cant talk to any one in my family Without getting critisised And sometimes my bro wont do that But I feel lost that he did that And I have no one to rely on anymore

I don’t know what to do

Do you think im overreacting,? Or What should I do,? Or Do you think that was messd up of him to do that to me,?
