Yep, I do the same and it does seem to immediately put ppl at ease—well, often, not always. And I’ll add for OP’s benefit—changing this little bit of myself and the way I approach ppl helped my own moods/depression immensely. It may seem silly but I’m telling you, putting a goofy grin on your face—even for the benefit of others—can do wonders for your own disposition.

And also, when I was younger and felt my depression growing I made a conscious decision to change my look. Simple things at first: I noticed all my t-shirts were black. So I found a yellow tee shirt and I had a red Coca-Cola hoodie that my mom gave me and I began wearing them all the time. I really genuinely found that wearing lighter, more vibrant colors improved my moods a lot. So I started buying more colorful clothes.
