In-laws and councilling - UK

Just wondering if anyone has confronted their in-laws about hurtful things that have happened in the past as to the reason why relations are so poor? How did it go down? Mine is to do with name calling, insensitive comments, crossing boundaries (kids) and how their drinking affects us. Because of COVID we’ve only seen them 3 times this year, and apart from indifference towards me they haven’t been cruel, they just don’t engage with me at all. It makes me feel very uncomfortable on every visit. I seem to have developed really bad anxiety over it and start shaking all over when they simply just call my OH once every 1-2 weeks. I am considering getting some sort of counselling, but everywhere I look it’s around £50 + per session. I wouldn’t even know how many sessions I’d need. Just wondering if anyone had some advice on getting councilling in the UK?
