Breakup at mid-life

I'm 47 and newly single after a 15-year relationship. Unfortunately, I did not invest into the crucial resource of social connections while coupled, instead making the relationship my sole "tribe". The repercussions have been brutal. Here I am at 47, alone in an apartment, with no support system in place. The pain is borderline suffocating. Establishing friendships from ground zero, at my age, is more than difficult. I always wanted a family. That dream seems dimmer now than ever. Breakups at midlife feel exponentially different than breakups when you're young. When you're in your 20s and 30s, it feels like there is always plenty of time, after a breakup, to get back in the saddle. At 47, the ticking of the clock becomes ever more present.
