7 week old fussy baby feeling rather down!

[Lauu]

hi, I'm new to this site and also a first time mum to a 7 week old baby boy, I'm 25 and feel like I havent lived my life still yet and now i cant.

I don't know if I'm posting in the right place but just really want to know if how I'm feeling is normal!
My baby has been very unsettled and fussy since he was born hes been put on nutramigen milk as the doctors thought he was allergic to his milk, hes also been put on ranitidine for his reflux.
He seems better than what he was but still isnt 100% he fights his sleep when hes awake all he does is cry this is day and night and when he does have 10 minutes of been happy he is such a lovely happy baby!
When he does go down on a night some nights he can go 6-7 hours so I do get some sleep so I'm not completely shattered.

on top of this I now have started to feel sad and down, I hate to say it and I wish I never felt like this but I miss my old life its selfish to say it really is I'm finding it hard to adjust to been a mum, am I just not cut out for it? i cant see any positivity for the future i feel trapped. My partner is helpful but feel he can do what he wants when he wants we are very close and do a lot of activities together before the baby was born and I miss that I miss not been able to sit and chill with him, I miss been able to get up and go for days out together or going to bed when I want to go to bed getting a bath when I want one and staying in it for as long as I want with no worries!

I'm scared of if anything happens between me and my partner and we split up I'm scared of been on my own with the baby even tho there is no reason to be thinking this!

we have lots of support around us which Is why i feel selfish for feeling how I do as I know some people dont have anyone, I love my baby but I feel like I've made a massive mistake and I hate feeling like this I just want to give him the best life and for him to feel loved but I'm feeling like I cant cope and I'm not cut out for this.

I've got an appointment booked to go see my gp and talk about how I'm feeling but I just want some advice from other parents am I bad for feeling this way? will it ever change?
sorry for the long essay but need it off my chest and need to know if i will ever feel myself again

I’m so glad I’ve found someone that feels the exact same! I’ve been worried to say anything in fear of being judged so thank you! I’m 21 and me and my partner were the exact same before baby, we adventured yo and down the country constantly and drove around all night having fun, when baby arrived all of that’s stopped. It’s quite a shock to the system, suddenly you have all your freedom taken away from you with this little person to take care of forever. HOWEVER, now my baby is 4 months old, we’ve slowly started going out with her, meeting up with friends, it’s no wild adventures like they once were but it’s better than the nothing we had in the early weeks! One thing that keeps me positive is that when she’s 1 year old, she’ll be able to travel in the car more, and more importantly she’ll be able to come on our adventures, because she’ll understand them more, and not have to be constantly carried about etc.
So in conclusion, IT WILL GET BETTER! You just have to wait it out a bit, which I know is hard, thinking your life will never get back to being the fun care free way it used to be, and it won’t completely, but if you choose to let your baby be a part of your fun when they’re older, it won’t be far off! In the meantime, make sure you have at least one date night a month, you need to have those times to yourselves to just be able to breathe and be your old selves even just for a few hours! Hang in there!
