Stress Anxiety Rejection Need advice!

Sophia
I'm a college student and I have a lot of stress whether it's school, family or job but nothing get to me more than relationship. I been single for about 2-3 years, I'm a pretty serious person when it come to relationship I can't just hook up with someone and has no feeling for them. The problem is every guys that approaches me seem very serious at first and typical me fell for them them then they left because they're not ready to commit. At first it was hurt then okay but now it been almost three years of having guys after guys after guys walked away out of my life after months of talking. I can't help it to be hurt and stress about it. It is hurting my self esteem. Every guys that walked into my life also said that I'm too nice, I'm too intimidating , I have my shit put together too well. Honestly what is that suppose to mean? I do would like to think that there is nothing wrong with me but after all these rejection it's hard to think not to.
