Friend troubles

Ok so here's the problem, sometimes I have issues with my self esteem (and the way I look), and so I'll go and complain to my friend. I know it can get frustrating to him, but for some reason instead of trying to reassure me, he yells at me... I dont get why... Even if it is frustrating for him to hear me whine, I dont get why he gets mad? Is it just me, or is this an odd reaction to have? He has issues with his self esteem, but his argument is that atleast he tries to fix what's wrong. He has a point, I'm not exactly doing anything, but what I dont understand is why he gets mad at me?

Thats really odd - maybe you complaining about your imperfections makes him think more about his imperfections, it could definitely frustrate him. Or maybe he feels like he has it so much worse then you do and hes thinking 'if only she walked a day in my shoes she would shut up' sort of thing. I know thats how I feel sometimes when someone in complaining about how bad they have it because I know that I have it much worse then them.
I think the fact that you do nothing about it has a big part in this because he feels no matter how much advice he gives you, your not going to apply it so he feels like hes just wasting his time.

I've had friends before who, like your self, have suffered from self esteem issues. I like to think that I'm a very understanding person and offer my advice willingly or even just lend an ear and listen to them vent. I have also had friends, who want nothing more but to talk about themselves and take advantage of my kindness. This usually results in contributing nothing to the actual friendship except when it's in their best interest.
I've also had friends that complain and whine about everything, to the point where it puts me in a bad mood. (ever hear the term misery loves company?) I call these toxic friends.
I call them that because usually when you invest into a friendship with a toxic friend, you get nothing but negativity out of it.
Now, don't get me wrong, I'm not accusing you of being a toxic friend here.
However, your friend may be starting to feel like the only reason you want to talk to them is because it's only in your best interest.
Or maybe it's because after talking to you, they start to feel bad about themselves. It's possible that they don't consider themselves a good friend because no matter what advice they give to you, you still seem to be upset. Or maybe they see the real beauty you have and get mad at you when you dog yourself.
Don't feel like you shouldn't be talking to your friend about things that bother you. Friends are there to listen and to help, love and support you. That's why they're called friends. Just remember that it's a two way street when it comes to a friendship. Maybe letting your friend know that you understand that will make them stop all the yelling.
