It was my birthday today and no one cared

I know no one cares I don’t normally do this but I have no one to talk to and just need to vent as I’m feeling kind of down right now. Well anyway it's my 18th birthday today, one birthday I was actually looking forward to as I don't normally look forward to my birthdays as I always seem to be disappointed. But this time I thought it would be different as people ‘encouraged’ me to do something so I decided that we'll go to the cinema to see Paranormal activity since I just thought “hmm why not”.

So I told everyone like 3 days ago the date, time and place and people seemed pretty excited to celebrate 'my' birthday but in the last minute / on the day of my birthday everyone decided to cancel on me for reasons such as 'I don't want to spend money on something I’m not going to enjoy so I’m not coming (“my apparent best friend”)' ' the movies too scary' 'the times are too late for me' ‘I might not have enough money’- 30 minutes later “omgsh guys my online shopping came up to a total of £200 the other day Lol” and I know that some of these are pretty understandable reasons but I just can't help but think that if this was someone else’s birthday e.g. my “best friends” there would be no hesitation in fact I know! That this is the case. As my friend recently had a birthday (the one everyone likes) and no one made any fuse about coming even though it was in the same place, ended at 1:30am in the morning, was a 2 day event, cost a lot of money since we went out to eat at an expensive restaurant. Also my other “friends” birthday is next week from today and cost £30 and everyone is still going regardless.

So in the end 5 people ended up cancelling leaving just me and 2 others which was quite disappointing since I was quite looking forward to spending time with them most of all .So I decided to cancel the whole thing as people were just giving me really dumb excuses such as “might be busy” coincidentally one after the other + these people are suppose to be some of my closest friends at least I thought they were.

But today has just made me realise that I hardly have any true friends, I’m friends with other peoples friends, friends with people by association and I know it kind of seems like I’m exaggerating but it's the truth and this isn’t the 1^st time. I also found out later that the reason why everyone started cancelling is because of ‘others’ cancelling and they didn't want to go if these ‘other people’ weren't attending. It’s quite stupid because I actually thought these people were my friends but today confirmed that they only pretended just to get closer to my other friends and don't really give a crap about me at all.(should’ve known I guess:/)
I mean I've experience this before ,I stopped talking to the people who were my (as some may say) 'fake ' friends I just didn't see it coming this time I thought people liked me for me not just for the people I’m friends with.

To add to this, most of my siblings also forgot it was my birthday + all Teachers (as they have a system where they give chocolates when your birthday comes). My Mum and my Dad who don't live with me also forgot it was my birthday (well every year anyway) and basically no one cares. I didn't receive anything I never do on a daily basis (I live with me Auntie - who also forgot and doesn't actually care) but I thought that maybe ,just maybe today will be the day I receive something to help with school and just in general.

I have exams to pay for which is going to be a struggle to get the money for since I live in a very antisocial, bitter household where I’m expected to cover myself financially since no one gives a crap. To be honest I’m just fed up I have no one and I’m not exaggerating ,I just use to act like I don’t care . I have no one, people probably don't care and to be honest I don't blame you but I just want to leave everything and everyone behind and never come back.
I mean this sounds pretty dramatic but I’m actually being very vague I’ve been experiencing neglect and isolation for about 17 years now, just suppressing my feelings acting like I don't care but today , today just pushed it , pushed it too far. I'm tired of having fake friends, I’m tired of having parents who don't care I’m just tired and the worst thing is I care so much I care so much about the people I thought were my friends I bought them birthday presents, I’m a true friend to them but yet nothing back.

This is the last time I ever care about anyone who doesn't deserve it.

Sorry about the length/grammar /spelling and all I’m just done. If people have any advice on what I should do about my fake friends it’ll be much appreciated.

Nothing rude please as I will just ignore.
