3 months constipation

Hello, im 21 male, just moved from PA to upper wi and I need help figuring out what to do, I moved here in August and for the 1st month it was all fine, during the first month I remember I didnt drink alot of water or eat alot of fiber it was mostly protein, but after that first month I noticed that I haven't pooped in a few days at most 3, so started keeping track and didnt poop for another day. So I went and got some miralax, I didnt know that it was supposed to be used for a couple days so I only used it for 2, it helped pass a little bit of string like poop but that was it, so I tried not eating and only drinking water for 4 days after the 2 days of mirlax and I was pooping very small amounts, so I went and got a pack of stimulant laxitivs which helped alot more, but it was still pencil like, I went a month and a half of this taking a stimulant if I notice nothing came out for a day, and im still on a liquid diet, just water, milk, fruit juice and some mashed potatoes since I was really hungry, after the 2 month mark I tried an ennima, that did nothing so I went to an urgent care, they did xrays that ill attach and told me to take half a bottle of magnesium citrate for 2 days and mirlax for 30, he also told me to eat fruits like apples and beans and things high in fiber, also to drink 93oz of water every day, so I have, I take fiber gummis 10g of fiber a day, an apple same time every day, whole grain bread and lots of nuts like almonds and sunflower seeds, I've also been getting more active since my job before I moved was alot more walking then now, im on day 27 of mirlax and while the poop is alot more each time I go and is a bit more formed its still mostly mush and nothing with very clear edges, its kinda like really mushy macaroni, and sometimes ill wait on the toilet for hours for nothing to come out, while its almost everyday now I get like a courter of my toilet full of mush some days I just wont go at all before this I had absolutely no issues, my metabolism was peak and I never had to strain to get anything out, I am lost, I dont have the money right now for another visit and this is just torture and I just want to know is this normal? Like when I stop taking the mirlax will it slowly start pooping normal again if I keep eating lots of fiber and drinking lots of water? Any opinions would be appreciated, also if anyone knows should I try another ennema? I got half the bottle down there sp maybe the problem was it wasent all of the bottle?
