Sometimes it's definitely important to focus on yourself, but, not allowing yourself to feel emotions and so on.. that isn't living free, that is living in fear of these things and you're making yourself prisoner to these things. Personally, you shouldn't not allow yourself these things just because of yourself and or people in your life making them not enjoyable feelings to you. It's all about the right mindset and the right people, you need to surround yourself with the correct people - if you continue to surround yourself with people that make you feel this way then they are more harm to you than good.. that or you're conflicted with these feelings and you'd rather reject than accept. This is understandable though, sometimes we have to take some time to reflect and think on these things.. it can take a few minutes to a few years to truly figure out what we really want and or think about some things.. but surrounding yourself with the right people and so on will definitely help you figure these things out. But I don't believe in not allowing yourself to feel these things, don't let fear or anxiety control your life or you will seriously regret it in the future. What I do agree with is being yourself, don't let others dictate how you live your life and don't revolve and adapt your life around others if it doesn't make you truly happy.
Keep your head up and smile more, as every person on the planet is.. you're one of a kind - smile more, forgive more and live your life the way you actually want to more.
