Lacking confidence and afraid

I've been climbing for about 6 months now and did my second V4 this week. I've been noticing a trend starting where I'm high up on a climb and the finishing hold seemingly requires me to have a hand on a bad hold (doesn't feel secure) then reach or/and do a dynamic movement up to the finish. It clicked today after trying a route with someone else and them mentioning their observations of my tendencies; that I do in fact put a lot of consideration into my feet because I am trying to place myself in the most stable position I can. This segways to what I think the crux is, when I feel I already don't have a good grip then taking a hand off will mean I'll fall/slip off. That lack of control, not feeling certain of my grip and position, therefore unstable, and not feeling like I can dictate when I'll come down makes me scared to take the risk and just go for it. Maybe physical and mental tiredness plays a part. I do intentionally focus a lot on technique because I want to be efficient. I'll add this has only been happening on climbs that go high on the wall. Any advice, suggestions, whatever may have helped you is appreciated!
