I really need help getting out of Bronze this season. Looking for a coach or something. Not paying.

Hey. I've been trying to get out of bronze for a long time now, and the start of s8 just fucked me over so hard. (I'm not asking for sympathy here; I'm just explaining what's going on and how I feel/what I'm thinking about ranked so far).

I've consistently played around the b3 region, ended b3 last season. I've consistently played with high bronze - low silver players. I have, multiple times, played with friends who have high silver and even low gold games and I hold my own (might not do super well but I'm not going 1/10). Point is: I am better than b5 and I know it. Silver? Maybe not yet. But I know I'm better than bronze 5 and I should be climbing, but I don't know / can't identify what's holding me back. Here is what I think of every time I lose a game:

I've been playing Katarina and Cassiopeia a lot in ranked, and I really can't do well with either of them. With Kat, everyone says she's such a good champion, but every tank seems to counter her since they just CC her to death or soak up all the damage.

Every time I play I feel like I'm countered in lane, or that the enemies are so much better than me. It's really frustrating since even when I try to play my best certain champions can cheese their way by and win anyway because they counter me in lane.

2-8 in placements. I had some good games, some bad ones. Eh. Even in the good games I still thought there was nothing I could have done. After placements. The first time I picked Kat I got an annie smurf who was way better than me; I fed really hard and got very tilted. Fine. Things happen, I took a break. The last game I played I got paired against vladimir; bot and top fed also which didn't help, lost again.

I know I've only played 2 or 3 ranked games + placements this season, but the same thing happened last season where no matter how well I did (I've had games where I steamrolled mid and yet bot still fed early and I couldn't do anything).

I always try to farm out the lane, go roam bot lane to snowball them, come back, farm a bit, roam wherever the team needs me. I'm always pinging mia, dragon, herald etc. and my team is sometimes responsive but sometimes they just blow me off. I always try to help my allies snowball, sometimes at the cost of my own progress since I know how much bot lane matters in Bronze.

I'm getting 30 LP per win and only losing 14, yet I'm still getting pounded into the ground. No matter how much I try to roam, gank, farm etc. it doesn't seem to matter, since one feeder straight up fucks over the game. If I lose I always take at least a 30 minute break; on bad losses I'll just stop for the day or a few hours. Nothing really helps... and I don't know why.

I really need advice on how to climb; I don't know how my friends got out of bronze in the slightest. I'm around the same skill level as some of my friends and play with them a lot, yet when it comes to bronze 5, the lowest skill level, I can't do anything while they can get into silver, gold easily. Eventually they will get so high I won't be able to compete with them. I

I also have no issue with normal (blind or draft). Those games always feel fair, and I actually do a lot better in those games even when I'm playing against a higher ELO team or with silver/gold friends.

I'll send in replays of my next game or two if you're willing to review it. Or give some advice please on who to play (mid). I love Kat and Cass but I don't know if I can play them in this elo.

(If it helps I have about 100-150 ranked games (maybe) and over 1,000 normals) Thank you.
