Trying to visit nan while in radiation surgeries in UK

Hello all. well I am originally from London England, but have lived in the usa for the better of my adult life,  I am at a point in life where I need a little help, I am always helping others, and am in need of help myself now, but seems like I can never get help when it's the other way around.  I lost my mum last year to Kidney failure, had not seen her in ten years then when I did get to see her it was in a coffin, I was having immigration issues then having to renew passport etc, it's just been hard for me I made two trips home last year, with my 15 year old daughter and now im dried out of pocket, my grandma was diagnosed with breast cancer last year and she is in her 80's she basically raised me, I am wanting to go visit her while she leaves Jamaica to go to London to undergo more radiation procedures, I just cannot affored it right now, I actually just two weeks ago had a so called best friend leave my home, from being here for 7 months, with her 4 of 7 children, she was being evicted and none of her family was willing to help her, so she moved from GA to FL inoffered her a place to stay, and it seems like her true personality came out while here, she didn't look for work, just lived off the goverment and didn't offer to help me with any bills like the light bill which was around $300 to $400 a month, she did give me $250 a month but when your sitting on your butt all day and using up lights and water and not trying to better yourself and all they did was drink alcohol all day and not want my advice it got real annoying, so trying to be the better person not arguing trying to make them feel comfortable, they left to go back to GA while i was at work, didn't even say goodbye, thanks mothing, she were always mad that they didn't have this that and the other but should have been mad at themselves not me I just tried to help, anyway, now there gone, it's me and my daughter and im just trying to start over, but wants to visit my grandma before it may be too late, any help would be appreciated, flights are usually around 1000-1200 per person, I hate to beg, but it seems like at the moment my CNA job isn't gonna cut it, and I am onma payment plan with the light bill and rent is paid, which that will always be I just won't seem to get ahead, I am also in school for computer programming,,amd finish next year. if anyone cares enough please help me in any way possible, Thank you in advance.
