Depression and anxiety disorders have symptoms to what you are deescribing. However these symptoms should be addressed by a professional. But for now, depression can include hopelessness, increase in appetite or sleep, decrease in these things, lack of motivation, fatique, irritability, poor concentration, lack of interest in activities that you enjoy, isolating oneself. Depressxion can be situational (temporary) or chronic and long term. When there is a thought that this is getting out of control please seek help. Anxiety disorder is a lot simpler because it involves anxiety of course. Sometimes people benefit from therapy without medication. Or sometimes you may be just going through a phase and therapy can be short term. Regardless you don't have to be miserable or unhappy when there is help out there
