Sounds like anxiety, OCD, depression to me. I suggest you go see a psychologist and talk about those things as you have to let your emotions out.
Healthy diet, medications, exercise are all things that could improve your condition.
I am new here too but, what your describeing sounds like OCD ( Obsessive Complusive Disorder ) and YES it can accompy Depression and will lead to anxiety and stress. Like a vicious cycle one will feed off of the other.
Have you gotten any counseling? If not hon I would highly reccommend you do. This disorder can be so painful mentally and lead to more mental issues. I wish you well
Good Luck, Best Wishes
your doctor will ask you to do a quiz 10 questions to determine what you have, im suffering from anxiety, my partner works 15 hour days and i have to look after our 2 young children all myself i cant even have a soak in the bath, i feel im drifting away because i hardley see him, your doctor should prescribe anti-depressant that will help depresion and anxiety, i feel miserable sometimes because i have no one to talk in the day
What you describe sounds like a major depressive episode with OCD and Anxiety as main features.
Leaving your home in the UK and being alone now a lot are significant life changes that often precipitate a depressive episode.
See a good psychiatrist and there is a great success rate in treatment.
