Finding positive people to be around - This really helps me. I used to have so may people that were fueling my depression and luckily they slowly got replaced by people who were fully supportive and who helped me know what i needed to improve.

Pets - I have two cats and they really help. I recomend a lynx point (looks like a grey tabby but with bright blue eyes. Very mild mannered and care about their owners).

Hobbies/work - keep your mind off it. This doesn't always work and results may vary.

Church/God - Giving yourself over to God helped me immensely. I recognize now how he was there even when i denied him. He is the redeamer of all and loves you. Plus if you end up with a church family they can be a constant source of support and strength.

Other people may have some other sugestions.

oh.. Helping others through their depression and trauma as well gives you hope and helps in your own depression.

Breathing helps. And I mean breathing with the only focus being on feeling the breath go into your lungs on the inhale and feeling the air being pushed out on the exhale. But I have depression and anxiety so it might be better for the anxiety than the depression. Hope you find something that works for you.

Thought of something else.... Finding things to be grateful for, and start small. Like with being thankful for the internet connection or some of 5 basics senses. And either write or type them out we each day.

Wonderful ideas here! Would underscore them all: helping others, positive people, gratitude, hobbies/work, pets (if you like them)
The only other thing I might add that has helped me when I'm feeling down is positive self talk. I've written down positive statements to make to myself like: "I'm capable of handling anything that comes my way" "I am loved just for being who I am, just for existing." If you want ideas, just google. You can pick ones that mean the most to you. Using them is what makes a difference for me.

And maybe self-care. Plan something you can look forward to--even if it's small. Do something kind and nice for yourself.

My pain management doctor recommended CBD oil years ago. I got the MMJ card and buy it with 0,2% THC which isn't not enough to see in P test - but since then my A1C, cholesterol down and stopped high blood pressure pills. All those meds were making my depression from "foggy brain" and lack of concentration much better. It may help you. No, I don't sell it - just use it. Good luck if you try.

these are great ideas. some stuff i do, get outside and walk, care for or spend time with an animal, getting enough sleep, certain foods do seem to help like salmon, spinach, berries. Just generally eating really healthy. Coffee and green tea staying well hydrated.

Keeping busy and don't be too hard on yourself.

Talking to family and friends.

My remedy for depression is to keep myself busy and focused on something. I have to "move away from my thoughts" or I can go down that rabbit hole fast. I quilt, play games on the computer, watch inspirational movies and Zentangle. Check out Zentangle on Pinterest. You can easily be occupied a few hours and all you need is a pencil or pen and a piece of paper. It is doodling at it's finest. Keep your mind occupied and focused on something and that will divert your negative thoughts. If I wake up in the middle of the night and my mind starts racing with negative thoughts, I get up and go to my quilting room. I can not stay in bed and continue allowing the thoughts to continue pouring in - I have to remove myself and get into something to occupy my mind.. Learn to Love Yourself. I'm still working on that one!!! One other thought - try hypnosis. Check out Marissa Peer on YouTube. She is absolutely wonderful. I highly recommend her. Her hypnosis has really helped me.

When I feel really bad it's hard to be around upbeat perky people. Makes me feel different and left behind. When I'm a little down it can be helpful to be
around supportive people

i found having a purpose to each day helpful. i force myself to join meetup groups - i find the walking groups good. it lifts my spirits that i have somewhere to go and mixing with people is good for me. i also like that they bring their dogs. Meetup have so many different groups some are on line. i do zoom meetings at night which also helps like for example meditation etc.
I am not saying that it will cure depression, but it allows me to forget about it for a little while. good luck
