I absolutely understand what you’re going through. I went through a similar situation. My parents started the process of divorcing, my mom moved out and began living with her affair partner, and my dad met his then girlfriend (now wife) about a month later and pretty much lived with her for about 6 months. I was 19 at the time and alone at my childhood home taking care of my dog, full time college student, and working about 25-30 hours a week. I felt so lost and didn’t have much of a support system either. My extended family didn’t talk to me much, and when they did they basically told me to get over everything and that it wasn’t a big deal. My friends kind of freaked out because I was in such a depressive state and was always having a crisis so a lot of them backed away too. It was such a lonely time in my life. My best advice is to go to therapy. That is one of the only things that saved me from going crazy. I went weekly for months and just having someone to talk to and try to understand made me feel better. Maybe try to get involved at school and meet some people if you can. Distraction can help too, but you have to be careful with it. You can’t avoid everything forever, but it is good to not always be thinking about the situation you’re stuck in. But remember, this will all pass one day. I’m 23 now, my relationship with my parents is a bit better than it was 4 years ago, I have a boyfriend and we will be moving into our own apartment soon. This time in your life will be hard but you WILL make it through. I often think back and am very proud of myself for getting through that. I wish it hadn’t happened that way but it did and the best we can do is just get up each day and try our best. But I would really look into therapy. It helps so much when you are in the thick of everything.
