There is no doubt you can recover. Here a few healthy advice's:

1. Post only quality content. No BS, no SPAM
2. Be consistent, do it every day. At least 1 or 2 posts per day
3. Dont push to much in building SP at this time. All SBD's you get - reinvest in buying upvotes from bots. Steem:SBD ration is so high now, no much use to buy STEEM or SP today, better collect upvotes through bots. Fat upvotes is what makes Reputation to grow faster. From other side, no much difference you will notice if you have 15 SP, 50 SP or 150 SP. Building SP will be your next phase.
4. Put a meaningfull and usefull comments. Engage. This helps to be noticed, and collects followers. And even brings upvotes. Commenting is just as important and usefull as posting your root articles on you blog.
5. Stay away from MEME's . Many hate them ( including me)
6. Have patience.

I have no doubt that by following these directions you can rebuild your reputation in 2-3 month .
Good Luck !
If I see a good content from you - I promise you will get my upvotes too. Instead of downvotes - which you got from me quite a bunch :)
