A lot of the time, especially as we grow older, after having gone through the kind of thing you have, it's hard not to feel like we're alone, or maybe just that everything is a little harder for us. You are not alone though, never forget that there are people around the would reach out if they only knew, they will not because of pity but because they too have questions and concerns about things that they need help answering. Whether you want to see someone on a professional level, or just talk to a friend, should be up to you. Most colleges and universities I am familiar with have counseling services, and many people on livewire would lavish the thought of helping someone else to feel more comfortable. Best of luck with everything, it does get easier.
