This does sound like depression, but there are many things you can do about it. To be honest I was just prescribed medication yesterday for depression and it's going to take awhile for the medication to kick in and help. In the meantime however, try and think about things that can be causing these feelings and try to eliminate as many as possible or find a solution to them. I can pinpoint exactly what is causing my depression and it's helpful to do so. Exercise can help since it's releases endorphins and will keep your mind on that and that alone. The sun always helps so depending on where you live try and be out in the sun as much as possible since it gives you vitamin d which makes people happier. Otherwise, talking it out with people is always a BIG help, keeping a journal to get all your feelings down. Try seeing if health insurance can cover a therapist? If you find you just cannot make yourself happy and need some help with it then antidepressants are helpful. I hope this helped even just a little bit.
He said he can't afford a therapist.
Many people have been where you are now and lots have come through somehow. Read my post to "alittlebitofrandom" a few minutes ago. For me it took meds to get my old self back, and a stronger than ever self it is, or at least smarter, I think.
It is important for you to be happy, otherwise if you really are clinically depressed, you can spiral deeper into depression through no fault of your own.
I read that only a few exceptional people can apply self-therapy to bring themselves out of a true depression. Odds are 50% that you will have another after your first and 90% for a third so please find some advice (from these posts or wherever) that makes sense to you and commence action.
I am encouraged that you mentioned that certain things used to make you happy, because perhaps things can right themselves once again.
Write back with feedback. Someone can help.
It sounds like classic symptoms of depression. If you can't go to a therapist, what about your family doctor? He might be able to prescribe a drug for you, at least for a while, to see if it helps. I don't know your age, but if you are older, some of these things could be from hormones, like in menopause. Also, I don't know your family situation or if you're married or have a boyfriend. You might benefit from counseling if you can get it.
