....how to get rid of stretch marks?

Okay this is embarrassing enough as it is and I hate to ask but what are some cheap and easy ways to get rid of stretch marks? I'm 13 bout to be 14, my height is 5'5-5'6 and I weigh 135ish (ive actually been trying to lose weight) im already really self conscious as it is and these stretch marks didn't help when I noticed how bad they are!! So they're on my inner thighs, hips, and even my boobs (oh no!) haha. Well for a few days I've been rubbing lotion on them when I wake up, after I take a shower, and at night. Then I read online that lemons help even the color of them. So I tried it out and it worked!........... For about 5 minutes then out of no where the stretch marks "magically" reappeared. Non of this stuff is working! Long story short I'm REALLY self conscious and it's summer wearing shorts, swim suits, all that. And Im really embarrassed if people see them. Please tell me ways to at least make them less noticeable and no rude answers thanks!
