90 days ago i posted here for the first time, my story sounded very similar to yours. logging on that day, and every day since has helped me not pick up since.
i still have a lot of work to do, but i can tell you that even after just 90 days, i feel much less lost and depressed than i did that first day. i still wake up every day with worries and the weight of responsibilities; but there is also this glorious moment each and every morning when i remember that i'm doing it. please believe me when i say that if i can do it, so can you. life improves a little each and every day.
