jealousy is ugly

So I dropped out of college when I was 18. I am currently 23, just now starting back into school to get my bachelors. My boyfriend is in the process of getting his masters, all of my friends are graduated, starting to get engaged, and are doing bigger and better things. Every time I see something posted on any sort of social media about my friends getting married and having kids, I get envious of them. And now I'm fucking stuck in college with people who I have literally nothing in common with. Don't get me wrong, I love college now and am so excited I'm even able to be going. But it's pathetic I feel this way. How do I get over this. I am disgusted I even feel this way. I know this is literally all my fault, but ugh.
