I am feeling the same way, to be honest.
I thought I’d be able to knit up a storm, being stuck at home for a month (I work for a non-essential business here in NV so we’re out til at least 4/17). Instead it feels like I can’t focus on anything for long.
So Wednesday I decided to embrace it. Instead of beating myself up for “succumbing to startitis,” I’m trying to acknowledge that yes, I’m worried and afraid right now, and so my concentration is suffering. So I’ll knit a few rows of a sock, then stop and do something else, then knit a row or two of my shawl, and so on.
I’m still feeling discombobulated but it helps me not to blame myself for the outcome of how I feel. And yesterday I got through an entire section of my shawl in one go (Steven West’s Fantastitch) instead of only managing a couple rows.
