This seems like a really strong possibility- perhaps something happened (either of your doing or otherwise), or maybe you were deemed ready for whatever it is that has opened up 
Another thought is that (and maybe I’ve been thinking too much on this week’s time magick challenge lol) it’s not related to the immediate moment, but something that happened this time of year in the past, or something that will open up for you in the future at this time of year.
I’ll skip right over the usual slogan then 
In addition to those options, I’d ask if you might have done any recent spellwork or manifesting? If you go back through your intentions, something there might give you an idea as to what opened up.
Additionally, the direction you are sensing could be a big help- if you draw a circle and call the Watchtowers (or designate the directions in another way), you could turn to face exactly where you feel the blockage and try to use that to help you work it out 
Just a few thoughts you might consider! Whatever it is, I hope you’re able to work it out, @anon87969570! You’re a smart guy- I believe in you 
Good luck and blessed be!
