whatdahell,
you just pass your 90 days of OPT no big deal. If you are STEM major then you are eligible for OPT extension. you can stay doing nothing for a year but you should be able to say/show that you are actively looking for a job. if you want extension then join any consulting company with your subject of interest. it will be very easy if you are STEM major. Tons of consulting company are there to provide you any IT training and place you in job and make you workhard and make themselves big chunk of money and hand you peanuts. But you will get something which far better than getting nothing as you are still unemployed.

Action Plan.
1) decide what you want to do stay unemployed or employement.
2) choose technology of interest i.e programming,analyst,developing,administrator
3) contact your friend if there are working with any consulting company or find consulting company yourself
4)starting preparing hard
5) get job and work very hard dont complain about peanuts you are getting later you will get good amount after having experience.
6) the most important part, After gettting job update us with good news.

All da best. enjoy your job hunting. ;)
