Why do I feel so unappreciated?

Because you try so hard to make things work, and sometimes we don't get the feedback we were hoping for. It doesn't mean people aren't thankful for our efforts, some things just get lost in translation.

The best thing to do in my experience, is to maybe look at all factors that may be making you feel this way. So grab a pen and piece of paper, what do you feel? who makes you feel like this? Then try and write senteces that pop up in your mind. Challenge those beliefs, are they true? do you think those things about yourself? Then look again at who or what makes you feel like that. Address the people/ situations as you think is best. Usually, we feel like this because someone or something has been happening for a long time but subtly.

Everyone feels unappreciated every now and then. It sucks. Often as people we forget that we can make others feel unappreciated and equally others can accidentally do the same to us. Understand someone always appreciates you and if you feel like no one else does, appreciate yourself.

it's easy to feel unappreciated in a world full of so many people. Focus on showing your appreciation and you'll always be able to give what you hope to get

That could be because you're actually underappreciate. Sometimes the world could miss out on some really amazing people and they may not get enough appreciation to what they do or who they are. If people don't pay you the respect or appreciation that you deserve make sure you stand up for yourself. If you've worked for it (every work counts even if it's not the best enough or not hard enough in someone else's eyes) you should be appreciated for it. If you feel underappreciated talk to the people who might be unconsciously (or at times consiously) not appreciating you for your efforts, try to make them see the point if they don't understand double up your efforts... If you're already doing your best, maybe it's time to leave toxic people. Be strong!

You feel unappreciated because you don't appreciate yourself, appreciate yourself please! You are you and I appreciate you.

It could be as simple as because you're not. A lot of things these days go unappreciated. We work so hard, and do so much, and rarely do people get the recognition that people need!

It's very easy to feel unneeded in this world. Especially with so many distractions and people taking things for granted. It sometimes does feel horrible when you're doing a lot of something/someone and it is never recognized. But you have to remember, we shouldn't do these things to be recognized. We should just focus on the fact that we are doing something.

The feeling of being unappreciated comes from yourself. You have to start believing in what your capable of then it will be reflected upon your action

That answer is best left up to you to decide. People often feel unappreciated because they aren't getting acknowledged or thanked for the things that they do and often it becomes a cycle. When you do things for other people, they normally appreciate them and forget to say it. So it is probably just a lack of communication from one individual to another, but that never means you aren't doing great things or doing something that is helping other people. Sometimes people don't notice or don't think to say anything. Do things that make you feel good and that you think to improve your life or the life of other and someone is going to appreciate it. Even if you are only helping yourself, you appreciate you.
