Cant figure out handstand

Been working on this for a couple years now , making minimal progress, I started with the kick up got decent but unreliable some days I could keep up and hold for like 10 seconds other days I couldnt balance no matter what, then I started doing front planche into handstand on like 2 bars got decent at that could go all the way up and hold for about the same but no more, now im moved to doing to the same with just my hands on the ground and I can work my way from a planche to handstand slowly and its all good until I get to the actual stand and its 50/50 whether I can hold it at all and even if I can its no more than like 5 to 10 seconds im close to giving up on this
