Do my colleagues hate me?

So I work in a cafe with 8 other staff members. Things were going great when I started there but then I started coming out of my shell and being the bubbly and joking person who likes to enjoy themselves while working. 

4 months into the job I got a verbal warning from my manager saying that someone said I stayed out till 3am and I was in work at 9am and I was tired but I came in and got my work done. One of my colleagues started making up lies about me and pointing out my flaws like I don't help out enough which is a blatant lie.

So after that was said I got my probation extended another month and basically if I step out of line I'm fired! 

I usually get ganged up on now, i get colleagues talking down to me and never get a friendly hello from my manager now.

I was supposed to go to a staff Christmas due but i pulled out because i don't want to be around people that don't like me. They said oh you'll be missed and I'll have a drink on your behalf but it is all misleading.

If my manager doesn't like me, the staff don't like me is there much point in me being there?

I feel very uncomfortable when I go into work and I'm afraid to say anything except if its work related.

Please advise me what to do. 

Thank you.
