Is it my fault?

Hi guys, so I'm going through a whole lot of situations, but I will say this for now, my friends and I were really close in high school, after graduation, they all seem to be doing successfully in life but I'm just stagnant, there are times I feel left out whenever we hangout because I'm always the odd one out. I really want to he successful too, I'm trying my best to get a good job and live life like my friends do, and nowadays, I really take their insults personal (I don't like it when they insult me indirectly due to my financial status and all) I'll stop here for now, I'm also a newbie in this app, looking to meet great individuals, thank you so much
