PLEASE HELP!!! Any kind of advice is so appreciated at this point

Okay to start with I have been dying my hair platinum blonde for over 2 years I’ve only used toner the odd time if it was a little yellow but for over a year I never touched toner it was just the blonde bleach I have been using the Schwarzkopf Blond Me Supreme Blonde Hair Quality Premium Care 9% 30 Vol Developer liquid and powder and only the odd breakage and it was only ever the roots that was topped up never the actual ends of my hair that was already blonde but I loved my hair. Keep in mind my hair has always been quite thin and fair🙈 now to the problems….

So May last year I decided I wanted to do a little pink in my hair (just the front two strands) now this is my own stupidity I thought I picked up a pink hair colour with no bleach…. I picked up a purple colour with bleach🤦‍♀️also…permanent. So because I didn’t get the pink I wanted I went out and bought the bleach London ROSE colour and just put it at the ends of my hair and around my ears. This didn’t really damage my hair I just had to top up the pink every wash and it was fine.

So I had noticed my hair had gone through more breakage so I decided instead of topping up my roots AGAIN I’m going to dye my hair my natural colour all over to match my roots…dirty blonde…. Well my hair went green and broke off even more so then I decided to put in a hair colour remover and I did it twice because I put 2 or so different colours of dirty brown in my hair and it was just different colours of green, orange and sort of brown… so I did what any sane person at this point would do…. I dyed my hair red to cancel out the green🙈well within 1 week of my hair being red half of the head on my head just broke off literally BROKE SNAPPED GONE. I was on holidays when this happened and I was absolutely gutted.

I have hated myself so much since I hate looking in the mirror, getting ready for work or to see family or going to concerts I feel so embarrassed of my hair I’ve bought 3 wigs for going out to help my self esteem but I feel horrible with the state of me and my hair.

I have tried to many different treatments and my hair still feels so thin and fragile I’m so heartbroken over it and it’s been 8 months since my hair broke off and the regrowth is so slow compared to before. I don’t know what to do anymore I hate going to the hair dressers as I’m a very anxious person and prefer to do just it at home but it’s at a point where I think I need something done to fix it. Would my hair be to damaged for extensions? I feel like if I go to the hair dressers they’d recommend a very short cut which I’d hate so much too😭

I have tried olaplex which I used for years in my hair and it was always amazing until my hair all broke off I’ve tried keratain treatments I’ve used redkin acidic bonding, live overnight treatment, batana oil, honey syrup, coconut oil, K18, 10-1 multi benefit hair masque and probably plenty more. I don’t have any set routine because with my job I work morning and nights back to back so it’s whenever I get a chance to do treatments and hair care I will.

I live in Ireland and would love any kind of help or any recommendations for hair stylists in Ireland or uk or Europe who could help me out if massively appreciate it I will attach photos of my hair and its journey the last year any kind of help is really appreciated
