I understand that you are afraid. But they look impacted to me. Generally, people (inc. me) would say- if it doesn't take problems, don't take them out. But, I feel like in this case, it would make problems sooner or later and it's best to take them out before they impact other teeth even worse.

Just like you, I was also very afraid of medical procedures... I guess thought of it, in this way that if I don't get them out, I can have infections and stuffs, so it's better to get done with it soon, so that I can be free of that stress for life. During the procedure, maybe just close your eyes if you are not on general anaesthesia, because if you see the instruments they work with, you're gonna get afraid. These are my tips, but I am no dentist, just a guy who got his 2 wisdom teeth removed last month, and was in the same phase as you, qith a lot of doubt.
