I don't mind admitting that I've had issues with my mental health in the distant past, particularly when I first had eye-sight issues over a decade ago. I also have PTSD from a past incident a number of years ago; not a lot of people know that but let's let it all out and lay the cards on the table. There's nothing to be ashamed of there, and if anything, one should be lauded for being so open as I'm being here. But please respect my boundaries if I don't want to discuss some things further.
I should add that I am not a mental health professional and I don't try to claim to be one, I don't run any kind of groups for it either, so I don't feel I can offer any advice on this issue beyond saying value your mental health. If help is needed, seek it from qualified professionals. I will speak (write) here only from my personal experience, which can hopefully inspire you to find your own path to mental wellness.
One of the most important things with my own mental health is to set positivity as a goal. It can be easy to get overwhelmed and find negativity in the slightest little thing. When feeling down, little moments of joy can add up. At one particularly low period of my life, sitting and meditating over a cup of tea, focussing only on the flavour as I drank re-grounded me to celebrate the good things in life instead of being overwhelmed by negativity. Little things like savouring the flavour of a good cup of tea helped me on my road to recovery a number of years ago.
It's important to remove negativity from your life if possible, or protect yourself against toxicity. One person I met had some rather nasty opinions on mental health; they were indubitably a toxic person, with opinions that would vary between saying that persons with mental health issues were just selfish, to saying that mental health didn't exist and people should just "man up". Naturally I didn't keep such people in my life. I am now surrounded on a daily basis by people and friends who promote wellness and positivity and support.
In conclusion, your happiness and growth is vital. Your mental health should be a priority. Your mental health is a necessity. Do whatever you need to do to ensure you can grow and bloom, and don't be ashamed of who you are. Be open, society has changed and those who are stuck in the past who want to try and shame people for speaking about mental health can get with the program and enter the twenty-first century. And don't be afraid to get help from the relevant qualified or trained professionals who can support you when you need it.
