Is it normal that i feel paranoid or depressed for no reason?

Yes I get this problem quite often I too have been institutionalized for depression it turned out I was puttin too much stress on myself and my hormones were telling me to slow down and take a rest I had suffered insomnia paranoia and I was put on a strong course of sleeping tablets it helped me sleep I slept for six days only getting up for food and toilet breaks it helped me a lot and was discharged I am now a manager of my own firm

Yeah, trust me, happens to me all the time. It may seem like ur the only one, but trust me when I say that just about every girl in particular deals with it.

Yeah most likely theyll give you ability or something like that. Just go to a therapist

Sounds like mood swings due to hormones, your age or depression.

Yes, it could be indeed be chemical. I have suffered from clinical depression (which can be cause by chemical imbalances) and it is really important to talk to someone about it. If you find that these feelings are controlling your life the it is time to take some action and reach out to someone.

I hope you feel better soon and take care.

just because you can't put your finger on the reason, doesn't mean there isn't one. who knows, could be chemical.
