Of course, it is always important to push yourself to do things out of your comfort zone. I've always been a big believer in this and I feel like I've been implementing it a lot in my life so far.
However, there is a big difference between making yourself uncomfortable in order to grow as a person or doing something that will only make you uncomfortable and set yourself back.
You can only tell the difference when you listen to yourself because you will be able to feel the difference.
The other important thing to remember, courtesy of my mother quoting 'The life changing magic of not giving a fuck' - it doesn't matter what other people think of your decisions.
Do not make yourself go through something you are not in the right place for, you need to remember throwing yourself into everything all the time is not the answer.
Remember to take care of yourself.
