Your not whining, letting off steam is very healthy, it's okay. The thing about life that you need to remember is it is filled with good times and bad. It's okay to feel bad because that means, at some point you felt good about something, and if something can make you feel good and happy once then it means something else can make you feel that way again. So you have to take the good with the bad, that is just part of being human. Your relationship might not have worked out this time, but that means you will find the right person who can make you feel that way again.
Keep in mind if you ever need to vent, your in the right place to do it. Hang in there, you'll be okay
