I think you need to take a big step back and take a look at things from a different prospective. Your parents took your phone and tablet away for a reason. They were most likely going to give it back. But instead of dealing with the consequences, you waste money to buy new ones only to have that taken away too. In terms of money spending, that is not going to help you in the long run when you want to move out. In terms of buying stuff behind their backs, it comes off as disrespectful, and to your parents, even rebellious.

I can understand why the did it. You do nothing but backstab people online. Yes everyone vents, but it can only go so far. Not only that, there is a good chance you are hurting people who care about you due to misunderstanding their intentions. And calling your parents psycho online isn't going to help. I think face to face counseling would help, as suggested by other posters.

Finally, as I mentioned before, as well as other people, start taking people's advice and think about what people tell you. Everyone here is very kind and are more than willing to help but when you repeatedly ignore everyone, disappear for a while, only to come back and make a post identical to previous thread, it comes off as disrespectful and makes it seem like you don't care about what people have to say.

Eventually people will get tired of offering advice and will begin to ignore you. I bet that is what's happening in real life too. If you ignored anyone trying to help you in real life, that could explain why they may be distant from you. They don't know what to say or do so they start to pull away from drama and negativity. Please try to understand where other people are coming from, rather than just assume everyone is a psycho in real life and ignoring everyone online.
