Ranked LP and MMR

I am fuming mad. I was in silver V and had a really bad day of ranked which tanked my MMR and put me in a horrible position for ranked play. This position is unrecoverable and I have dropped all the way to Bronze 2 now. I know I am not this bad but when my MMR matches me with players of lower rank and I cannot communicate with them without being flamed or reported for verbal abuse because my advice is taken negatively I am put in a position where I cannot recover from the damage done to my MMR and I will probably end up falling to Bronze V where I worked so hard to climb out of. It also didn't help that immediately after being demoted I lost 3 straight games where my LP was dropped 25, 25, and 26 LP respectively. I think the worst part was at one point I was steadily climbing and almost won a series for Silver IV and now I am about to be demoted and fall back into the Elo hell I took months to get out of.

I guess my point is that I see this as unfair. I am not claiming to be a Challenger God stuck in elo hell but I do know I deserve better than the teams I am getting put on and the toll of a loss on my LP. I will not lie, sometimes in games I have a bad game and do not perform to a standard that would win the game and I respect losing LP for that however even in games where I am performing above the MMR I am cursed with I still get so much LP taken from me and my MMR tanks to rock bottom. I am not sure what I should do about this and the problem is just getting progressively worse as I get on worse and worse teams that are toxic and blame others. I just wish the ranked system could be revised to judge players as individuals rather than their ability to synergize with people who are potentially the worst players in the game.
