Sharing Our Innermost Thoughts

My (step)dad is always so mad and I don’t know what to do anymore. I’m 17, turning 18 in July, and he’s been my dad for about 11 years now. I love him a lot and I’m glad he’s in my life, but I’m so tired of his temper. When he’s mad, he’ll do one of three things- mumble angrily under his breath, stuff like “no one in this house does anything fuckin right”, he’ll stomp around and practically throw things he’s moving or handling, or he storms off somewhere else, usually his and my mom’s room. Sometimes he yells and it’s always scary, even when I’m the oldest child. He used to yell a lot before but he’s done it less over the years. I know his life is hard with 3 kids, one going into college, and his work life is absolutely shit. But I wish he would at least try to work on himself a little and not be so mad all the time. I want my dad back, I’m tired of dealing with a fifty year old toddler throwing tantrums every week over work or other stuff. I don’t think talking will solve the issue, I’m scared to talk to him about major things because of how he just sighs and acts like it’s a huge burden to even speak to me. I’m exhausted and I wish I could do something that’s not just going to make him more mad
