Asma, I can relate to your experiences. I am a college junior with bipolar disorder, and my journey has been difficult.

Have you considered seeing a psychologist? Your college most likely provides free and confidential counseling services. Starting college can be a challenging and scary experience. It's possible that this is factoring into how you are feeling.

Even if college isn't the main aggravator, and you have some kind of underlying mental condition -- a counselor will be able to help you out, and refer you to the right resources. For example, she'll be able to tell you whether to see a psychologist/psychiatrist, how to approach professors for help, etc. Most professors are not intimidating at all, and are happy to help out a student who is struggling, especially if there are medical reasons. Of course, you won't have to divulge everything to them, but having a (brief) note from your counselor or disability services can help the process.

I'm always happy to talk if you have any questions. Feel free to send me a friend request, and we can take our discussions to private messaging if you want. Take care, and good luck.
