Hey Jessy
I am sorry to hear that you are going through this difficult period. I can definitely relate. I am around your age (21) and I have friends with very similar situations. I too am almost finished with college and I am in crisis mode about what to do with my life/where I am and where I want to be.
I think at our age feelings like this are completely normal. The one mistake I ALWAYS make and I hope that you can avoid making is comparing myself to everyone around me. I think a healthier way to think about it is to understand that everyone is different and has different paths and different ways of going about doing things. For one, you should be immensely proud of yourself for sticking with your Bachelor's and graduating this May. That in itself is something that no one can ever take away from you and that you achieved all on your own. Try to replace negative thoughts with positive ones. Work on your own goals with weight loss and don't think about trying to find someone right now. I think what would be better is to get yourself to a position where you feel good about yourself on the outside and the inside and then maybe put yourself out there some more. We are both SO young and I think society rushes us into becoming older than we are.
The bottom line is that I am sure you are a very unique person with wonderful qualities. I always think of this point in my life as a critical juncture- just like it is for everyone else. Sometimes people part ways during this time because of life situations/new interests. My advice is to stick with your old friends but maybe branch out and try to make some new ones who value the same things as you. Don't feel too lonely, we all go through periods like this I think.
Message me if you'd like, I'm here for ya! *Hugs*
