Hi,

I feel the exact same as you, where I feel great and the next moment I am very sad and hopeless of getting better. I have been suffering for 7 months and my doctor diagonosed me with Mild Depression and I am seeing my psychatrist in August for the first time. It is hard to deal with and family and friends have a hard time understanding what it is like, I am comforted by a lot of positivity which is keeping me good. I have gained a lot more weight so maybe getting to the gym will help. But when you feel no motivation it is tough.

I would reccomend you to go see your doctor, you could have what i have or maybe something else. There is treatment out there for us and we will get better.
