should i be mad at this? my friend never puts any effort towards me.

Actually no not this time. It's the older friend that I have that was like a mentor of mine. For the last couple of years I feel like she has really taken me for granted and advantage of me in a way. Let me know if you agree. Every time we plan a get together it's always been with me driving down. ( she lives close to my parents ) but for the past few months I have not been driving down every weekend cuz of hurtful family stuff. And she knows this. so for the past few months I have only been driving down 2 hours only cuz we had plans. And not just once but every time she waits til mid morning on the day of the get together to tell me a time and place when I'm waiting to hear from her cuz if we weren't getting together I wouldn't be driving down at all. So I have been jumping in my car driving 2 hours to see her when she only has an hour to spend with me and it's been only an hour every time I see her ever since I've been married. She only teaches part time and both her kids are grown and out of the house. But the reason why last weekend was worse was cuz she knew bills grandmother was ill and that she could be passing any day so that was more of a reason why I wasn't going to drive down at all if we didn't have plans. So Wednesday of that week I was sopposed to tell her either Friday or Saturday by wednesday so that she could still plan her weekend and I did that I called her phone and left a voice mail and said in it I needed to know if Friday was ok and to let me know either way so I'd know to drive down or not. So she never gets back to me til Friday around 9am. On the day of our visit. So I made myself get up early to wait for her. So when I heard from her at 9am. I drove 2 hours and when I got there she acted like nothing happened. And she only had just an hour with me and she knew I had to drive back that evening cuz of bills grandmother passing. She's been doing this for the last 4 years and I always bend over backwards for her all the time and it feels like she's taking me for granted and taking advantage of me. And all of this hurts so much cuz she knew what was going on and she said nothing like it was ok or she has started to expect that I always make the most effort. And it's just really draining me. And I know I can never say anything cuz the last time I did and was honest with her she got mad and made me feel like I was wrong. Sorry this is so long. I just really feel hurt by this.
