If they're bothering you that much, perhaps stepping back from them a bit followed by a gradual re-introduction will help you.

Tell you instructor about your difficulty & ask if you can do a period of slow flight ~5-10 kts above the stall. Get used to flying around at this speed in different flap configurations. You'll need to add power during turns.

Once you're quite comfy with this fly with the stall warning just activating. Get used to stopping it by reducing AoA, starting it by slightly increasing AoA. Again, you'll need to coordinate power during manoeuvring. Focus also on being able to maintain a heading with wings level ie use rudder to PREVENT yaw away from the desired heading. Use a distant surface feature as an aim point.

Next step is to take it to a power OFF stall in straight, unaccelerated flight. Just like in the previous exercise, stop the stall by reducing AoA. The goal is for you to CONTROL the process. You could, for example, stop the stall just enough to leave the stall warning activated, or recover to a slow glide. Don't forget the wings level/no yaw thing. After getting comfortable with flap up stalls, progress to increasing flap settings.

Next is to stay in the stall for a period while still holding the heading. Recover after a while eg500' height loss. Ditto the flap settings.

Now do a straight stall, recover and use power to minimise the altitude loss. Don't rush the recover at first. Take you time to transition through all the previous stages you've been practicing. Add power after the stall warning stops. Start adding power earlier & earlier until you are comfortable doing this pretty much simultaneously with the other recovery actions. Ditto the flap settings.

Next is power on stalls. Start with minimal power, building up to climbing stalls.

Do the same process with turning stalls. Start with power off, shallow AoB. Build up to increasing power & bank angles.

Depending on the a/c type some combinations of flap/power/turns will cause more abrupt stall behaviour than others. The goal is to leave those ones until the very end of this process. Your instructor will know which combinations are more benign & these are the ones to do first eg it might be that stalls up to 20 or 30 deg AoB are more benign than climbing stalls. Fine, do those before climbing stalls etc.
