Iterate through Map to increment count

Hi,
My apex code doesn't not increment the count. Can't find out Why.
Could someone help?
Thanks
Apex class: 
public class FeedItemTriggerHandler {
    public static void countFeedItem(List<FeedItem> lstFeed){ 
        set<id> relatedCasesIds = new set<id>();
        for(FeedItem fd : lstFeed) {
            if (fd.type =='TextPost')relatedCasesIds.add(fd.ParentId);
        }
        Map<Id, case> relatedCases = new Map<Id, case> ([Select id, caseNumber,All_Users_Feed_Count__c FROM case where id in: relatedCasesIds]);
       	List<case> casesToUpdate = new List<case>(); 
        
        integer count = 0;
        for(case c:relatedCases.values()) {
           for(FeedItem fd : lstFeed) {
               if (fd.type =='TextPost' && fd.Visibility =='AllUsers' && fd.ParentId == c.id) {
                   count+=1;
                   
               } 
       		 } 
            c.All_Users_Feed_Count__c = count;
            count = 0;
            casesToUpdate.add(c);
              
        }
        if(casesToUpdate.size() > 0) update casesToUpdate; 
    }
}
Trigger: 
trigger FeedItemTrigger on FeedItem (after insert,before delete) {
    if(Trigger.isAfter){
        if(Trigger.isInsert){
          FeedItemTriggerHandler.countFeedItem(Trigger.new);    
        }
    } else if(Trigger.isBefore){
      if(Trigger.isDelete){
          FeedItemTriggerHandler.countFeedItem(Trigger.old);    
        }
    }
}
