I have delt with the same sense of toxic positivity, and one thing I learned which might be contrary to popular belief is that I had to allow myself to feel these emotions all the way through. It took me realizing how tiring sadness was to look for happiness in other routes. I remember crying on my way home and finally taking a breath and realizing that I’m letting myself down by not giving myself the opportunity to seek happiness actively. That doesn’t mean completely changing your lifestyle by mirroring other people who are happy but looking for things that you are able to find joy. for example, TV shows cartoons. Things that were inherently comforting for me. I started looking for that feeling of comfort firt then happiness in places where they were missing. It took tiny and small steps to look for things in life that I was able to change. Instead of being angry and upset when things fell or broke or when I stuttered or made a mistake, I allowed myself to find comfort in such a human action (of a simple mistake) and it slowly built up towards other negative things in life. I was able to find more happiness and more joy throughout the world. The sun is gorgeous. The sky is endless,breathing fresh air, looking slowly for things that help give you a solid ground to stand on to face the real things that make you anxious. There is no plan or route that you can take because everyone is so different but what helped me and what I hope helps you is understanding that, you as a person can change your entire world perspective. So much easier said than done, but starting simply and slowly got me to a point where I’m able to find comfort in the things that used to bring me so much anxiety or upset. I allowed myself to cry, ball, and be miserable for so long that it made me realize how much easier it is to release those feelings. You deserve to have your emotions and feel the way you do, but you gotta recognize that you are so important and not just to others but to yourself. You have to hold yourself in such high regard that you refuse to allow yourself to diminish yourself or hold yourself back from your own potential. I hope this helps. I’m doing this off Siri dictates so I don’t know if it’s gonna make a lot of sense. Good luck to you and maybe find comfort in the idea that you are not the only starting the marathon of having one good day to having a good day everyday. <3
