Many losses

In the past two years I've lost 8 people. Anywhere from old age to car accidents. Two of my friends committed suicide. 5 of them died in different car accidents. The other was my great grandmother. I don't know where to start. A lot of people have told e to 'get over it'. Or that I'm overacting. I went through a deep depression for about 7 months. It's gotten better. But I still feel purposeless and unmotivated in life. I have Jesus. But I feel stuck. I feel like I'm getting nowhere. And no matter how hard I try to process through grief if just doesn't work. I don't know how to process grief. Especially not 8 different losses. And that's just in regards to death. Those 8 losses aren't included in the loss of my car, loss of a few deep friendships, and going through my own personal car accident. I don't know how to heal. I don't know how to get better.
