I'm mad at my friend who was just trying to help.
Is him trying to help what is making you mad?
Yes, he just loves to help which is very annoying.
Try not to get upset with someone who is simply wanting to help you. If you honestly do not want any help from them then do your best to let them know in a kind way.
I don't need people who are always pushing their help on me and irritating the fuck out of me.
Maybe you can tell them you want to figure things out on your own. You shouldn't get upset though for them being a good person.
