How do you get Motivation?

I (27f) constantly feel a lack of motivation for literally anything. I should be in my “prime” bought a house we’re renovating, engaged etc but I’m REALLY struggling to find motivation for anything. I don’t have motivation to workout to “look hot for the wedding” (October), no motivation to plan and organize my stag and doe(July), plan a wedding, etc. it all just feels so overwhelming with so many decisions and details. How do I “get in gear”?
Should also note; I am the worlds best procrastinator and also have some lingering depression which don’t help ofcourse. But any tips?
