You may be scared, hurt, angry, sad, anxious, nervous, crushed; overcome with every emotion other than being okay.
It's easier to heal if you let things be, take their own course. Accept that you need healing. If you need time to heal, take time - don't push it. Personally, I don't think you really can push it. If you're not okay, you can mask it - you can try to hide it from yourself, as you can from others - but you cannot truly 'un-feel' the emotions you're feeling. You can disguise, yes.
To disguise or not - there's no right answer to that. You may not want interference, questions or curious eyes and ears prying upon you - I know I wouldn't. When you're hurting, when you're unsure, the last thing you want to think about is others' opinions of your feelings. If your feelings don't have enough space to breathe, it's natural to not want to give that space to another's.
'Supposed' - how much I hate this word is probably a matter for another day. Let me just put it out there, that I don't appreciate being 'supposed' to be or do or say anything. I need to just be.
So, well, I think it's okay to think about yourself. If you're not in a good place, I know how difficult it is to look at a situation from someone else's point of view. It's okay to not want to be in someone else's shoes when your feet are sore.
It's okay to not be okay. It's okay to think about yourself. It's okay.
Here's a good write up on Thought Catalog on this subject. I agree with every word. :)
