Losing friends is one of the toughest things to go through, especially if they've been there for you for your whole life. Trust me, I've been through this and I know what it's like.
If your friend is ignoring you or not being that close to you anymore, I hate to break it to you, but you may need to let them go.
There's still a chance to hold onto your friendship however. Christmas is coming up, so I suggest giving them a gift of a scrapbook with all your memories and see how they react. If they laugh, cry and thank you for all the memories, they're worth holding onto to. If they have a blank expression or embarrass you, you have to let them go as they aren't your friend anymore.
I tried holding onto one of my friends before and I did exactly this for their birthday. Her reaction was 'um... Thanks?' And chucked it in the bin.
I let her go and stopped being her friend.
A few weeks later, I started college. I was nervous as I didn't have anyone close to me in my class so I felt it would be hard for me to make another friend who I could get close with.
Then I found my best friend... Let's call him Bob as I wanna keep him anonymous.
I was assigned to sing in a band and Bob had messaged me before on Facebook 'as mentioned in the depression chapter' and that was the first day I spoke to him in person. There was also Jim and Fred (keeping anonymous) who were in the band. They made me feel so comfortable. I became friends with them straight away.
That's when Jill and Patricia walked into my life (I think you get the whole anonymous thing by now).
Patricia also walked out on being a mate of mine and I was sad, but I still had Jill and Bob.
Bob then introduced me to Clive.
Basically, what I'm saying is you don't have to try to hold onto your friendship. I didn't, and now I have many other friends who will be there for me.
I'm not saying give up on trying to be their friend, keep trying, just not as much. If they don't put the effort into being your friend, why should you put the effort into being theirs? Find someone worth your time and you'll eventually grow to make more worthy memories with this friend instead of slowly losing the memories with your old friend.
I know this sounds harsh, but it's the truth.
If you have trouble finding a friend, I'm always here! My details are in the depression chapter on how you can get hold of me.
And finally, if they treat you like nothing again... Just listen to the crow and take advice from the crow!
I love you! :*
