Do you ever feel like you aren’t good enough?

Do you ever feel like you aren’t good enough and that the world is against you? Well, that is how I feel. When things happen to me that I get upset about, I get all depressed and I feel like I can’t do anything. Everyone thinks that I am all happy 24/7 but I’m not. I have feelings that I keep inside of me and then when things get too hectic, I start having a panic attack, I feel like I shouldn’t be here and I just want to curl up and be left alone. The reason why I keep things inside and to myself is because I feel like if I tell someone then they will tell other people and then things get spread around. The reason why I just act like I am happy is because if people find out that I’m not happy I feel like they would just make fun of me.
