jealousy is an ugly trait😞

I hate how much I compare my life to others. It's gotten to the point we're I've become extremely unhappy, and I'm ruining my relationship. I want so badly to be engaged/married, having kids, buying a house, just getting to the "good part in life". But I made the choice of dropping out of college 4 years ago and just now starting to take classes again at the age of 23. My boyfriend is working on his masters, and I just feel so left out of my friends group because they're all doing what I consider, bigger and better things. I know this is all my fault, but I am so mad and disappointed in myself.Â
