Transmission for Vehicle

Before anyone thinks that this is a selfish reason for making this just let me explain a little bit... I am 21 years old an i am a father of 2 beautiful little boys, Abel who is 2 he will be 3 in december an my youngest Liam who is 1 an also a husband. I have been working basically ever since i was 17 years old which is when i found out i was having my oldest an ever since then it has been an up hill battle but me an my wife have always found ways to overcome those battles... I am a man with a strong ego an a man that is so hard headed that i never ask for anything from anyone but for whomever is reading this at this point in time I'm so desperate for help that i don't know how to overcome this obstacle. My trucks transmission had went out about 2 months ago an we was staying with some friends so for that time we had some help getting me to an from work an getting my son to his doctor appointments because he has frequent appointments every week due to his autism. He sees a speech therapist an a occupational therapist, but during that time of saving up money for a transmission the truck already had some more issues with it so me an my wife decided on spending $1500 which is not an easy amount of money for me to come by on a van at a little mom an pop car dealer ship after getting the van we found us a little house in pascagoula so things seemed to start going pretty good for us or so we thought after moving here the van that we got had ran into some problems like some kinda expensive issues so we took it back thinking that the place would help us out an see if they could fix it or do something at least considering that was the only vehicle we had at the time so they said yeah they would so i had my boss tow it to the place for me an we get a call the next day stating that we was not gonna be able to get our van back which made us kinda confused because we was never late on our payments but he said that we ruined the vehicle an destroyed the computer inside it which was impossible because the van would crank up when we dropped it off an with a destroyed comouter in a vehicle you can't crank it up... So basically the whole point of this is that I'm in desperate need of help to make repairs to my truck because me an my family have no vehicle whatsoever an im doing my best to save up the money for it but it just seems like one thing after another is just happening in our lives that is preventing me from saving the money for it.. I feel like such less of person for not being the provider an dad that i should be an im feeling so ashamed for having to even make this fund me thing but im out of options here my son needs to get to his doctor appointments, i need to get back an forth to provide for them an it is all just so stressful. If anyone that reads this had made it this far thank you at least for taking your time to look over this but anything at all will help my situation... God bless you all any and all help will to towards getting my vehicle running. If anyone has any questions about anything at all regarding anything just ask
