I think I can offer some helpful advice.
First of all, you should not be crying. you should be celebrating and I'll tell you why. It doesn't matter what you have accomplished if you are looking at everything under a microscope. You need to commit to doing what you are doing for at least another month or two before you start accessing if you winning or losing. This is the first major dip you have gone through and it hurts to think that you will make X amount a day and grow that and then two weeks later you are struggling at times to make 40% of that. You are judging yourself on too short of a timeline. It's like being an NBA coach and being mad that you have lost three games out of 40 but you are only half way through the season and the playoffs are still ahead. Just put things into perspective.

To your questions.

Would you help me understand what I do that is most valuable for our community because that is what I need to be focusing on? You share a lot of content on your posts and you post several times a day. The thing is you only have 800 comments. That is really low. You need to engage more with the community and learn the art of curating content to get rewards. If you voted and replied to late minnows or early dolphins, you will start getting a lot more rewards passively. If you reply to more of your followers, it will also build a stronger bond. I would strongly recommend just finding posts you like an upvoting and engaging and then on your posts engage more with your fans.

At the same time, would you help me see what I need to give up doing because this will make time for me to focus on the rest?
Cut the things you like doing the least. I feel like you were very optimistic about what you could accomplish but you didn't factor in a 60% drop in STEEM. I also feel you are associating your Steemit worth to your value in your wallet. You can't do that. Get back to focusing on the things you like best about steemit and do more of that. Cut the chat, build relationships on your blog instead. Jsut focus and don't worry about the short term and set long term goals. Where do you want to be at the end of the year? Then work towards those goals without focusing too much on the day to day.

I hope that helps. Now just put things in perspective and get back to work. You don't need time off, you just need perspective and focus. I believe you will do it.
