Why am I like this with pain and sadness. Should I get a therapist?

Those problems totally suck, that must be really really hard for you. therapy can help, or just seeing a psychologist. It is nothing to be ashamed of- life is yard to deal with sometimes, and especially if you have had suicidal thoughts, even if that is rare, it is reason enough to seek help. God can also help you, so you could seek help from a pastor or try to find inspiration from the bible.
