How to get over a breakup?!

So me and my friends (all male) we hangout a lot at my place, even when I don't feel like it, sometimes I just don't have the energy, but if they called me I always say yes, btw we have been friends for 6 years now, so one day they got invited to a party at someone's house, we all knew him well, here's the thing they all went to it without even telling me or invite me to it, fyi I figured it out by calling them to hangout as usual, but they told me where they at and ghosted me,

I immediately got mad at them because we always hangout at my place and I felt left out and used,

And now they are not speakig to me.

I need an advice and did I overreact?
