Almost 22 ..never had a boyfriend.. Im tired of looking.

My life has always been really hectic with all the responsibilities that I had on my shoulder.... When I was 17 I moved to US and I had to take care of my dad and I was getting ready to graduate from high school... When I went off to college I was just starting to have some fun ... but it was at the beginning of the second semester when my mom was diagnosed with Metastatic Breast Cancer, and ever since my life has changed in many ways.In college there were few guys who liked me , but since I knew they were not my type I just pushed them away. My biggest problems are my self steam and my social skills, I always think I am too fat and ugly for any guy and I cant seem to be able to show my interest to guys that I like..As I said in the few past years my life has been a challenge .... I am a full time care giver now, I moved back to home with mom which is a challenge because I cant connect with people here... I am taking my classes online.. and so I am always too busy to meet anyone here. I have come to the conclusion that I am going to be single for probably few more years maybe 5 or 6 ...but its so hard for me to be ok with that.. with the situation that I am in right now, I some times just need some one to hug me and tell me that they are going to be there no matter what. I just want support from some one more than a friend.... and its so frustrating that I don't have it. I just dont think if I'll ever meet anyone. Im so damn tired of looking for the "one"..
