yeah that's definitely either depression or anxiety. you should really talk to your doctor about it...and it also helps getting support from other people. if you feel as though you need help, go with that instinct. another good way to determine it is if you don't enjoy any fun activities, would rather sleep, or if you begin to think about suicide or hurting yourself.
and there are different forms of depression as well, so there isn't just one distinct classification.
it does sound like you might be depressed. if you're weapy and not wanting to leave the house, ect. this is easier said than done, but you need to find some people outside of work to hang out with. that will get you out of the house and stuff. or even like singles groups or friendly activity groups (you can look some stuff up on meetup.com). it's hard to get out of the rut, but you have to "fake it til you make it" as my therapist would say. chin up :P
Thanks very much.
I don't know why but I also just feel embarrassed about talking to anyone about it
It can be hard to talk to people about how you feel at first. I've gotten to the point where I talk freely about it with my doctors (that's what they're there for!) and sometimes my parents. Do talk to someone though...don't want you feeling down anymore :)
