You came to the right place! Coming here and sharing your story and experiences is a good place to continue to heal. Welcome to HW! There are so many supportive people here, and it really helps sometimes just to get things off your chest.
You are so not alone in how you feel. So many people are in your same situation. I don't remember what started my depression, though I did have a lot of stress in my late teens. I've been on a few different medicines myself, and like the others have said, it does take a while for them to fully kick in. I have been on meds for a while, but I still also have good and bad days. I personally feel that if you don't, then you're on too much or the wrong medicine. I have taken medicine in the past that made me a zombie, and I didn't feel anything, good or bad. That's when I changed medicine. Sometimes it takes changing medicine, or the dose to get you to where you want to be.
Sleep is a huge issue for a lot of us here also. A lot of us have either a hard time going to sleep or a hard time staying asleep. I can get to sleep, but I wake up a lot, and often feel unrested in the morning because of it. I'd talk to your doctor about it, and they might think it's a good idea to take something to get your sleep pattern back to normal. Sometimes they'll just give you something short term to get you back to sleeping again. They can also offer suggestions on things to help you sleep better.
I hope you find HealingWell as much help as I and many others have! Keep posting and let us know how things are going for you.
