First off, Welcome to HW! It sounds like you are really going through a rough time right now. I am not positive, but I think in order to be diagnosed with clinical depression, it needs to last for weeks. If you have already been depressed for a while, I would suggest you see a professional to get help. If this is just a very recent thing, maybe you could try getting out of the house more often. It must be really tough living with someone after a breakup.
Can you go out with friends, learn a new hobby, attend a movie, go to activities at a church/temple, sign up for something with the park district, etc. That will give you a chance to meet new people, as well as limit the amount of time that you have to spend at home feeling depressed about the breakup & not being able to escape that.
I know you say you are very shy. I am too. I've found that it is a lot easier to participate is structured activities like group exercise classes, discussion groups at the library or volunteering at the food pantry, rather than just going to parties, bars, etc. where I have to try to take a lot more initiative & keep up a conversation with a complete stranger. Even activities like going to the quilting circle where the other ladies don't really talk very much is relaxing for me b/c at least I am not stuck inside my horrible little home (I'm going through foreclosure right now, so my home is not exactly a happy place either, though for different reasons), feeling sorry for myself and knowing I need to get out in the world but being afraid or too apathetic to actually go anywhere.
I will share that the longer you stay inside the harder it will be to try to reconnect with outside activities. I learned that the hard way & as much as I don't always feel like it, I do now try to find activities that I enjoy & force myself to go out. Once I'm there, I usually really enjoy being around people, but it just feels dreadful up until about 2 minutes after I arrive & have to talk with someone (whether or not I know them). The more you get out, I think the better you will feel. Give it a try! :) If it doesn't work, you could always try counseling or meds.
