How can I stop being so emotionally sensitive?

As a 21 year old, I recognize that I'm far from being completely emotionally developed. But, I also recognize that I'm way behind others my age. I think I am too emotionally sensitive. Things people say or do really affect me. Whether I care about the person or not, I always have extreme emotional episodes after others express their feelings or opinions about me. If what they express is derogatory, I get very upset. If it's positive, I get very happy. And, I absolutely cannot deal with rejection. I want to be able to just ignore what others think and just deal with what I think. How can I achieve that goal?


Do male-identified people have body image concerns?

1) My boyfriend, who I have been dating for a while now, says that he is fat and I don't think he is. He is built, but he isn't fat. And he talks about it all the time, and I just don't know what to say to him. He said that when he used to talk with his other girlfriend about it, that she would say, "well, go on a diet," and he said that made him feel like he was fat. And I don't want to hurt his feelings, but I know that by losing weight, he would feel better about himself. But I like him for who he is and how he looks. But what should I say to him when he says things like he is fat, do you think I'm fat, etc.?

2) I am a male, 24 years old, height 5'10", and currently I weigh 143 lbs... When I was 17 or so, I weighed a hefty 190 lbs... at that time, that really had a negative effect on my self image, and now at 143, I still don't think I'm thin enough... I have lost all my weight 100 percent through diet and running about 20 miles/week... but I don't eat enough and I always worry before I leave home if I "look ok"? Do I have serious issues?!?


Are other drinks besides water still hydrating?

I frequently hear that beverages with caffeine or alcohol are not good for replenishing fluids and preventing dehydration. But in reality aren't they just a bit less effective at hydrating your body than other beverages? In other words, if you were stuck in the desert with nothing to drink but beer, coffee and cola, would you actually be worse off and die of thirst sooner if you drank these beverages versus not drinking anything at all?


Is mixing uppers and downers a bad idea?

Recently, many of my friends have been doing methamphetamines. Often when they start to come down, want to come down, want to "level" out their high, etc. they take Xanax!!! Now I know Xanax is an anti-anxiety drug, and meth speeds your heart up. So can mixing the two ("reds" with "blues") be especially bad? I keep trying to tell them that it doesn't sound like a good idea...but they know that I hate pills so they DON'T listen. "They know better!" But I haven't been able to find any info specific to my question in other places. CAN YOU HELP?


Am I bulimic, or is it just a phase?

I am a college freshman and I think I'm on my way to becoming bulimic. Since my junior year of high school, I have periodically binged and tried to purge, but I was never really successful and it was never frequent. My senior year I made myself semi-successfully throw up for the first time, but it was gross and scary and made my throat bleed and I stopped. However, since I've gotten to school this year, I feel like things have gotten out of control. I started out eating healthfully and losing weight, because I am about 15 pounds overweight and need to make a lower weight class for my sport. (I am at a high level and compete internationally.) I'm also terrified of the "freshman fifteen" since I've always been chubby at the least. I couldn't keep up my healthy eating and snapped, and now I binge all the time and for the past few weeks have been throwing up. I think I could stop but I'm not sure. Am I bulimic or just going through typical freshman food phase?

Thanks for any advice.
