Help me please i feel like ending it all

I NEED HELP so bad with regards to my training plan.

I’ve been struggling for more than 4 YEARS with ZERO PROGRESS at all and it’s taking a huge toll on my mental health. I’m feeling extremely terrible with my progress, if i compare myself 4 years ago to today, i have made absolutely ZERO progress.

2021: i could do a straddle front lever, half a rep of OAP, bad adv tuck planche

2025: Straddle front lever STILL, not even half a rep of OAP, bad adv tuck planche STILL

my training progress consists of:

1. Negatives or OAP attempts
2. rope assisted OAP 5 sets of 3 reps (using number of fists as progress)
3. front lever straddle raises to full negatives 5 sets 3 reps
4. front lever rows 3 sets 12 reps

i’ve tried EVERYTHING. Increasing frequency, lowering sets, adding more volume all for no damn use.

i even tried going for weighted pull ups which i hit +55kg 1RM, my OAP did not even move a single cm, no progress with FL at all either.

i’m keeping track of my nutrition, making sure i hit adequate protein using a macro calculator, making sure i hit 8 hours of sleep (even if i sleep late), making sure to have rest days in between

my stats are 185cm, 76 kg

I’m so extremely frustrated and unmotivated with my absolute zero progress while i’m seeing everyone do a full planche in 6 months of training what am i doing wrong?????????
