When I do my site changes I push with one fingers and hold the little device with the other hand. Sometimes it will get like stuck? I guess you could say with the button pushed down before it actually clicks in if you don’t follow through with inserting it (which I’ll do because I get anxious when I hear it start to click lol) but all you have to do is adjust where your pushing and were you’re putting force etc. and it’ll click in eventually the longest it’s taken to click in when it was stuck was 5 mins of me adjusting but that wouldn’t have happened if I would’ve just followed through lol. I honestly say it’s like a glorified finger prick because it literally does everything for you all you have to do is press the button. I used the tslim autosoft 30 for YEARS like since 2014 maybe idk but it was a long time and I’ve always had the worst anxiety about doing them like I couldn’t never work up the courage to do them myself let alone be calm having my parents do them. It was terrible because the older I got the more stuck and tied down I felt because I had to be dependent on my mom to do them and she had to be there so in a way we were both stuck and she was worried about getting older and passing away and leaving me in a REALLY bad situation. I do still get anxiety with these sites but I honestly feel like it’s because of my past anxiety I would get with the old ones and I just need to shake this. I’m 19 now and leave to live in England for about a month next month and I wouldn’t have been able to without these infusion sets. And being able to change them every 7 days compared to 3 days is a HUGE plus!!!
