HELP! bronzie problems

Ok so its pretty obvious as to why i'm her asking for help. All bronze/silver struggles are real. I didn't believe in elo hell for a while as i began to climb slowly to s2 but keep dropping to s4. For about 2 weeks now iv'e been fluctuating between s3 and s4 and it's killing me. Majority of the issues are as usual, feeders,people who give up immediately after 1 death, and rarely afk players. My match history is full of near carries and hardly go negative but cant do much late game with 0 tanks. I recently switched over to top lane to fill in a tank role because majority of the games i'll lose is because we have 0 engage and get blown up. Alot of ap supports and squishy teams. What do I do!? I rage sometimes and say why do that? But try to keep as positive as I can. It's quite hard to not get pist after losing streaks you shouldn't be on in the first place.
