<p>OP, I'm sorry your first semester has been so rough. I mean that sincerely (as sincere as I can be on an anonymous website) because I've was depressed in the past. It can be tough when you feel isolated in such a competitive environment and everything seems so impersonal.</p>
<p>But go out and do SOMETHING. Take a yoga class. Take a dance class, even if you suck. Look for postings on the board at Sproul Plaza. If you don't have time to do this, make time! Even if it means sacrificing a little sleep. (Yes sleep is crucial but so is interacting with other humans)</p>
<p>For studying, try earplugs. They block out the little background ambient noises, for me it really helps. Sit in the front at your lectures and look at your instructor when she/he is talking (when you're not writing your notes that is).</p>
<p>If you don't like your living apartment try not to spend much time at home. Find a nice coffee shop or cafe for just hanging out. If you're studying at home, which you dislike to begin with, your study sessions will be less than stellar. The lighting is better in libraries too! </p>
<p>And remember, you will not be at Cal forever. If you're constantly thinking "omg 2 more years of this :-(" it will feel like forever though. Take things one day at a time. I know, easier said than done, but not at all impossible.</p>
<p>Best wishes. Be strong and prove to yourself that you can do it! </p>
<p>...btw sorry if I'm coming off as a pompous ass, I'm extremely extremely intoxicated</p>
