You sound a bit like me when I first started with anxiety and depression. I would get so down when I slipped backwards and wasnt feeling as good. Just know that up and downs are normal in recovery, and it doesn't always feel like the 2 steps forward, 1 step back, 2 steps forwards, sometimes it feels like 2 forward, 2 back, 3 forward, 4 back lol.
For me it's been a long term recovery and still ongoing but I have many other problems complicating it for me. One thing that really helped me though was to stop being so focused on getting better and starting to focus on just living my life and making some progress there. It started as simple things like, watch a movie and enjoy it, maybe go 10 minutes without thinking negative thoughts while Im watching it. I try not to think of the down periods as "Im not getting better, Im getting worse, I'll never get better" which is what constantly went (and still does) go through my mind, and started to just view it as "oh great, here is another crappy week to get through" Because you will pick up again and feel better.
Given the short time frame, I would think of it as all part of one illness and recovery rather than relapses. If you feel that you aren't making progress then talk it over with your doctor. There's no point worrying about it excessively yourself but it's also important that you make sure you are moving in the right direction and having a professional that can oversee it is important in giving you that support and comfort that even if things arent getting better right now, in the long term you are on the right track.
