Try to keep my fake friends or get rid of them or is it just me?

I have a lot of trust issues. My mom left me when i was four for crack cocain and heroin. i moved in with my grandmother, she would come back about once a year for a few weeks and be with me telling me she was going to stay but every time she would leave. i would get so happy and believe her even though she left me before. i left my grandmas house at 14 to go live with my dad because i could not take living with my grandma anymore. i did not really know my dad, but i soon found out, he was doing crack cocain also, and a whole bunch of bad stuff happened to me there. i couldn't trust or depend on him either. i even slept outside underneath a church mailbox in the middle of winter so i did not have to be around him or his friends. anyway, i got with my boyfriend at the time, and we were together for about one year and seven months. he was the only person in the world i felt i could trust or depend on ever. well, after that i found out he had cheated on me. possibly multiple times and was bragging about it. i was in such shock and deep depression because i could now never trust anyone ever. anyway, now i am 22 years old and i have a few friends i talk to that i have known since kindergarden. we used to be really close at times. i hate to be alone. i have always been this way. i am now a stay at home mom, and have been for the last 5 years. i don't have a job, or go to school, and my husband is always tired when he gets home from work. i call my friends to try and talk, or hang out but they never answer their phone. even when i have a problem or get severly depressed, no one answers their phone, or calls back. but i always hear of them hanging out. the only time i talk to them is when they have abselutely nothing better to do, they want something, or when ever it is convienient for them. when ever a friend calls me, i always answer when possible or call back and am always there for them. and when i tell them i will do something, i do it. i don't tell them we will hang out and then not show up, not answer my phone, nothing like what they do to me. i feel as though they may be causing me more stress than actually helping. but the problem is i can not stand being alone. i hate it. but if i stop talking to them, i will have abselutly no one ever to talk to. i litterly go days without stepping foot outside my house or talking to an adult except my husband for a few minutes before he goes to bed. i get so mad because i am always there for everyone else, but no one is here for me. i feel like they are all fake, and i can not trust anyone ever. do you think i am just crazy, or should i just let it go, stop talking to them, or what should i do? i always jump so quickly to answer the phone even when they ignore me for so long. it is hard and i can not take this any more. but once again, i hate being alone, i hate having friends i can not trust or depend on, and it is about impossible for me to be the way they are. what should i do? or am i just crazy.
