At 23 (almost 24

) I am the most fit I have ever been in my life! I feel great, but along the way of transitioning into someone who is actively seeking a healthier lifestyle have gotten some of those people who are on the
"I-think-it's-socially-acceptable-to-eat-whatever-the-hell-I-want-
because-I-don't-give-a-damn" in my face. Telling me I am too skinny, mocking my dinner/snack at work which consists of a whole piece of chicken, romaine leaves, some croutons, fat free
Italian dressing and some vegetables. Or When my boyfriend said to me tonight that he wanted to go get food and said it was "hard dating you" because I am so conscious of what I eat.

(trust me I let this fume out of me later that night and I ended up in tears because it's so aggrivating to hear people, especially him to critisize what I want to do with my life)
Now don't get me wrong it's not that I want to go BACK to how I WAS I just feel like there's so many people out there who don't get me and why I want to be like this and so in turn I should just say $#%% you and move on, but for some reason I have let others get to me more than I ever have in my life.
It has made me second guess my decisions and that's something I can't even believe I am doing. I know for being 23 I should know not to let this happen, but...lately I have been feeling a lot of stress, sadness (not necessarily chronic depression or something I need a pill for) just everyday stresses of life and relationships and that feeling of just not knowing where to turn to for answers.
I feel like exercising and taking my aggression out on some HIIT would do the trick, but it hasn't been cutting it. My well-being is mostly what's being affected because of all the psychological stuff that's coming from others twisting my normal mentality...
...any suggestions on something to relieve all of this??:confused: I try screaming in my car haha but that only helps for the moment
