@Charlottteee Yeah, it can be the start of depression, i had it, didin't treat at time and had severe depression, seak help as fast as possible, but try to identfy on your life if exist something or someone that is the cause of such feelings, if not it can be hormonal imbalance (the same as me) if it's the first you will be a step ahead when you go to a psychologist, so it will be fast to treat, and if it's the last you will only know when you go to a doctor, either way you need professional help, so go as early as possible to not regret later....(as i did)
