@emvic8100 you are not alone! I graduated from Cal aeons ago but I can remember my first semester like it was yesterday. I was lonely, intimidated by the level of competition and workload but at the same time excited and thrilled to find new things to discover being at Berkeley. You’ll settle in and eventually make some good friends. I made bonds with people on my floor and with classmates. Your 3.77 is great for first semester so please don’t beat yourself up. I promise things will get better but try to switch your routine up. I found some favorite cafes to study in when Moffitt was crowded. I browsed record stores and boutiques, ate at Blondies, Top Dog…you get the gist. Just carve out time to enjoy Campus and the surroundings to refresh yourself. Four years will go by fast. As for the boyfriend issue…not a good idea for your first two years. I didn’t ‘get’ a boyfriend until junior year. Trust me, you don’t want to be joined at the hip so soon and so young while at college. That happened with some of my girlfriends and their grades and stress level suffered and they eventually broke up with their BFs and were emotional wrecks!
Your life will turn out fine…I know a few doctors who are great, smart, etc. and they did not go to a well known medical school. So just try your best but remember to take time to enjoy life a little bit 
Good luck and best wishes for your remaining years!
