I wish you could be upvoted more.

If you feel sad, unsatisfied, inadequate, guilty, lonely, or demotivated when you shouldn't feel so or for a long period of time, quickly fill in this questionnaire. Odds are it's not something objectively wrong with you or your environment, but you simply got depression.

Depression is both serious and treatable, so the earlier you find out about it, the better it is for you. Depression is not some fatal rare disease, you can have a milder form of depression and not even know it about it. Yet it is very incapacitating. If you find that you have depression, however mild, and can't afford a therapist, find a book Feeling Good and start reading and working through it.
