You need to get an answer from your parents to understand there point of view then talk to them so they can understand your point of view. You say you feel like everything you do is wrong,but from I've read it doesn't seem that way. It's sounds like you based what's right and wrong from what other people say and think, not from what it truly is. Just because people say it's right or it's wrong doesn't mean it is. It's all about your intentions. If you lie to someone, but only because you wanted to protect them and that was your true intention than you were in the right.
Don't suppress or/and ignore your feelings It's not going to help your situation. Face it HEAD ON! I'm not going to lie to you it's going to be brutal but I promise you it won't be like that forever as long as you keep moving and you don't get stuck. You can't get people to like you for who you used to be because people grow and change that means you too. Find people who like you for you.
When you like someone it shouldn't be looked down on, it just means your human. It's in your DNA. I understand that when everyone around you is saying it wrong/right it will be tempting to believe it, but has it occurred to you that maybe only one person truly believes that and everybody else just jumped on board expecting to ride into a non-existent sunset and your the only one to realize that the non-existent sunset is exactly that?Non-existent.
If your feelings are becoming to much to handle and things are getting worse. See someone there's no shame in that.
Good luck I hope all goes well
