I want to become a vegetarian

OK, so I seen a documentary a few days ago that really freaked me out and ever since then I just can’t look at meat the same anymore and I thought about coming a vegetarian not a vegan because I still do like cheese and stuff but I just don’t want to eat the animals and I don’t think my family will be against it, especially because my dad is already kind of like that like he only eats fish and tries to stay away from dairy and stuff and on the occasion, he will eat chicken, but not all the time but the problem is I really love food, especially wings beef sandwiches, hotdog stuff like that so I was wondering, do you guys have any tips to make it easier especially because we might be going to Chicago soon to go on a trip with my family for Easter and all the main spots there for food are literally meat
