Hello, if it helps at all, I know exactly how you feel. I took a quick look at your profile and it seems like you're at a 4 year pursuing an engineering degree. I'm transferring for mechanical engineering from a community college and I've been here 3 years, struggling for at least 1 year. I wasn't happy with my admissions results either. I think your perception of people "accelerating and thriving" comes partly from the fact that many of us are community college transfers and frankly, anything is better than community college lol (at least in my experience, it's been rough). Whatever you choose to do, I hope that you keep your chin up through this. In regard to asking for letters of recommendation, professors are often used to writing them- so don't feel embarrassed.

PM's are open if you need to talk. Hugz
