I understand this completely and fully empathise with you OP, I have had similar phases of my life. Not appearing to be depressed or sad just… meh.
I went to counselling and it turns out I was ravagingly depressed and hadn’t even realised it.
I think there are a number of people who are born sad and being ‘happy’ and ‘fulfilled’ is a hugely laborious task. However working on yourself and prioritising yourself does make it better.
On an unrelated note do you feel like you may in some way be neuro diverse? I was diagnosed with ADHD in my early twenties and I found my sadness was partially due to my constant need to mask and put on a front to appear normal and that left me constantly exhausted and miserable.
However I do also understand what you mean about wanting to disappear. My mum once described me as the saddest person she’s ever met and that really stuck with me and gave me the drive to start counselling, I would really recommend it. I had a lot of unresolved childhood trauma that finally allowed me to begin to heal. Baby steps but I always tend to reflect on my progress at this time of year and I’ve come so far from the me ten years ago who drove to the petrol station on Christmas Day and bought a full 20 pack of Marlborough and chain smoked them as I sobbed.
Please don’t feel there’s anything wrong with you. There isn’t, so so many times people feel like this and it’s such a taboo subject it’s barely talked about. Everyone has felt like this at some point.
Something that always really helped me was on a brighter day I treated myself to some new pens and a pad (a real pleasure for me) and I wrote a load of notes about activities or plans that made me so happy, stupid things - slow cooked spaghetti bolognese and garlic dough balls for tea or a sims expansion pack, a new shampoo, conditioner and making a big effort with my hair one night - and every time I felt sad and ugly and worthless I would go into the jar and take a little bit of me and make a proper effort to put some effort into myself.
Consistently doing something that made me feel good no matter how small set up the foundations of giving me a more positive outlook.
My DM’s are open if you ever want to talk x
