I don't know what to do?

OK so I went to the doctors for my anxiety a while back and they recommended CBT, so a few months after that I had an initial assesment where a lady just took some details and asked me questions about myself, my anxiety, family etc. She said that I would have a nice young woman named Natalie that I would do CBT with which made me relieved because I wasn't comfortable with having a male therapist. BTW we couldn't ask who we wanted to have.

A few weeks later I had an appointment scheduled, except it wasn't with Natalie, it was with a man. I forced myself to go and told myself that it will help and that maybe I'll have Natalie and this was just a one off. For starters, the receptionist told me I had the wrong time, when it said on the letter 1pm, but she insisted it was 2pm even though I had proof on my letter, I couldn't argue back or defend myself because I was too scared, so anyway I went away and came back an hour later. I got to my appointment and he asked the same things the lady did, except I just didn't feel as comfortable as I did with the lady, it's nothing personal but I couldn't see myself going through with this therapist. I don't know if he was supposed to ask these questions but because I'm not a white person he asked if I was born here, if my mum was born here and if my dad was born here, all 3 of us were. I'm sure that it was needed but it felt a little weird. Anyway I got the session over and done with and felt worse than I did before but I was scehduled with another session in 2 weeks, I eventually had to cancel because it clashed with an important college class (and the fact I didn't really want to see him again.) I text him to let him know I had to cancel and then he rang me multiple times but because of my social anxiety I'm unable to answer or make calls and also I was in a class so I ignored the calls and turned my phone off. He then text me saying how I needed to contact him to make a new appointment, I feel so rude but I couldn't force myself to text back, I know it probably sounds stupid but I really didn't to talk to him ever again.

Today I got a letter saying that if I do not contact him by next week my CBT will be stopped because it will no longer be needed.

I'm unsure what to do, I don't even know if I need CBT anymore, I mean if I can't force myself to make an appointment do I really need one? I can't tell my parents because they will shout at me and say I'm stupid, I really want help because I have a problem, I don't have any friends at college due to my social anxiety making it hard for me to make friends but I really don't think I will be able to tell this man anything so nothing will progress, is there any online CBT available?

Thank you for reading, I appreciate it
