I agree, it's not the worlds faught we depressed. It sure makes it easier to blame everyone else though, been there done that but didn't do me any good.
I refused to take the medication though, thats just masking the problem. You need to deal with it, not cover it up.I went to counceling and got help. There are some free clinics for those who can't afford it. And hospitals usually have some free classes for folks with different problems or issues.
You need to make your mind up 1st that you are tired of being depressed and do something about it to change your outlook. Try treating yourself to something nice to get you going. And tell yourself every day how much you love yourself and how great you are. You need to have confence and love in yourself if yu want others to be same.
