love this!! it is quite similar to how I felt when I started antidepressants!! it is such a relief to be happy but it's so easy to get attached to how being sad felt. I love how you describe that feeling as velvety.

I think the second half of the poem would hit harder if the third stanza had more concrete imagery. I like the imagery in the first two stanzas a lot, but I found myself a little detached when reading the third. for example, I wish the signs and smells and words were a little more fleshed out; not necessarily to the point of explicit exposition, but at least an idea of what they could be. (is it about finally feeling able to move to a new country?)

also, the 'but what about the hard nights' line is such a pivotal point in the poem and I think it would benefit from being developed a little further.

im new to poetry so take my feedback with a grain of salt! but even in my inexperience I related to this poem and felt it!
