he literally hates me… I can tell. I have transferred to new school and this counselor is so rude…
I am worried if I get bad rec from him that would hurt my chances to colleges…
What can I do?
A counselor’s LOR is a must, for almost every college I have heard of.
Even though he/she might be rude, he/she might not be heartless. I have met so many teachers who are strict and rude because of their tight schedule but never destroy their student’s life. Especially a counselor should not do that.
If he/she really hates you as much as you think, there is no other choice but to improve your reputation. Be polite from now on and make sure you remain around. Don’t just try to ignore him/her. Make your presence felt, positively.
At the end, the recommendation may not be great, but it won’t be bad either 
Have you considered why? Or perhaps it’s just your paranoia - you may think s/he hates you, but in fact, s/he really doesn’t.
If it really is the former, you need to scrutinize your every behavior. Were you arrogant? Did you lie? Most importantly, what did you do to the counselor?
I really don’t think your GC hates you, but may dislike you for whatever reason.
Before pointing fingers, always reflect on yourself first. Good luck.
It’s hard to figure out how a GC at a school you just arrived at could know you well enough to be overtly hostile unless you did/said something that upset him or her. In any case, assuming you’re assumption is correct (although it just sounds a bit paranoid - you probably just got the GC on a bad day), make sure you have good letters of rec from everyone else, since they will know you much better. And do your best to be pleasant and polite with the GC - a worst their rec will be a neutral.
I wonder if you could also supply a second LOR from the counselor at your former school.
First talk to your parents and get their input. If you believe you have a good case, go talk to the school principal (maybe bring your parents with you).
OP, your only other post states that you are worried about getting a good teacher recommendation. You also stated that you are depressed. You need to get counseling and therapy either through your school or your family doctor. Talk to your parents about this now!
Based on TomSrOfBoston’s post, it sounds like you are having a very tough time with the transition to a new school. I agree with TomSr. completely: You should definitely talk to your parents and get some counseling to help you deal with the depression. Know that seeing a therapist is like getting your car tuned up - it’s just a smart and mature thing to do, not a sign of mental illness, weakness, lack of coping skills or (insert your favorite stigma here). An objective third party to give you some perspective and help you over a tough patch. Do it now.
Make him like you. It’s really important.
Are your other LORs good? Frankly, at a lot of schools the CG just submits a profile of school and your transcripts, not really a LOR like a teacher would send - most schools are too large for GC to know students that well. The biggest thing they seem to responsible for is checking the box that says you took the most rigorous coursework since they know the ins and outs of scheduling (ours also included cover letter explaining a magnet program).
