Thanks so much for taking the time to send us an email about the way things are going at home with you and your parents. The relationship with parents is one of the most important relationships in a teenager's life. We can imagine how upsetting it must be for you to feel like you can't get along with them. We know things feel overwhelming right now, we believe you...but what you gotta believe is that it doesn't always need to be this way.
It sounds like your parents are having some trust issues with you. From reading your email, it seems like they might think you are up to no good a lot of the time, even though you say that you aren't. That clearly creates some tension. Trust is something that can be rebuilt and repaired. Talk to your parents about this lack of trust. What have you done to lost their trust? In what situations do they typically not trust you? How can you prove that you are trustworthy? All of these would be great questions to ask in that type of conversation.
When you talk to your parents, it is important to pay attention to more than just the words coming out of your mouth. Your voice tone and body language also say just as much as the words themselves. If you get upset, emotional, yell, blame them, or get sarcastic it will just end up escalating the situation even further. Instead, talk to them when everybody is calm. Let them know that you aren't talking to them to argue, you want to improve the relationship that you have with them. You understand that trust can't be repaired overnight but you are willing to do what it takes to get it back.
Talking to the parents can be tough, so here is a link to help you:
