Hey, If you tell yourself it is worth it and the waiting time for LSAT is bearable, then it must be worth it.
You are still young, and the political environment will thicken your skin to prepare for the real deal.
I have read on this MB some self-protection/strengthening exercises that may help you. One example is visualizing the white light protection, whereby you stand/sit up straight and imagine a circle of light above your head that slowly envelopes your whole body and travels through your chakras to protect you from and cleanse out negative energies. I tried it yesterday and again today when I felt most stressful. I actually could feel my body "shudder" out the bad vibes and immediately calmed down. This exercise really worked for me. The advice is to practice this technique once in the morning and once at night. You may want to check it out and see if it helps, especially against those negative jibes.
Good luck with the LSAT. I know you will find a way to make it happen.
