Haircut dilemma !

Hello boys and girls!

I am in a huge dilemma here :( I have been thriving to let my hair grow as long as it can grow, unfortunately my hair hasn't been the same since I was like 13 years old, when I decided to go to the hairdresser and do some super ugly highlights (yes, I've told the hairdresser I wanted super thin ones and she made them 3cm wide -.-)

So my hair is really thin and I don't cut it for 6 months already. I used to go the hairdresser every 3 months for about 2 years but she always  managed to cut what my hair has grown every single time so I gave up.

Now I feel like I should at least go trim my ends because they're getting split and my hair really doesn't seem to have a shape anymore, lol. But I am sooo scared to go there and find a cutting frenzy hairdresser that just cuts EVERYTHING and I come back to stake 0. I am obviously not going to the one I've been going to for the last 2 years because she seems to get really distracted talking with everyone around her and it's my hair that suffers all the effects after :(.

I don't know what to do, should I just let it grow and go cut it when it's actually super long or just go soon and just BEG to the hairdresser to cut my ends.. ONLY! lol.
