You're verbally abusive when you're angry and that's not okay under any circumstances, no matter how stressed or depressed you are.
I don't think you were together 6 months and everything was going great. If this was an isolated incident and completely out of character for you, I could see a woman understanding that in a moment of pressure you lashed out. This has probably been an ongoing issue and this is just the final straw that pushed her away.
I think you're now upset because that "fat slob" walked away when you never thought she would and you lost control and that's really what's upsetting you. You're extremely lucky she has any contact with you at all.
