Please help! I think I have body dysmorphia.

So for a long time I’ve had pretty low confidence in my body, and I’ve taken a lot of unhealthy measures to look better. I workout every day and eat healthy but my body just isn’t good enough. Sometimes I even throw up after eating bc I feel like then I won’t have to work off all the calories and the fat. I constantly compare myself to everyone else and can’t stop. But it’s like one second I’ll have pretty good confidence, but the next second I hate my body again. I’m most insecure about my stomach, legs, and hips. Even though I subconsciously know that I’m skinny and healthy, I feel like I’ll never be skinny enough or thick enough and it just never ends.
