Needle phobia but really want to give it a go

I'm 8 months sober and found out yesterday that in that time I've gained 4 stone, so I need to start eating healthier and exercising and I'm in 2 minds if I should just do that or give mounjaro a go at the same time. I've read through a lot of posts on here which have answered a lot of the questions I had already but I haven't found many about the actual injection. I'm a bit (a lot) of a wimp when it comes to needles and it's honestly the only thing putting me off. Anyone else that's the same about needles was it better/worse than you were expecting and did you get used to it after the first few?
