Sudden panic attack. It worsens kind of.

Every night before I go to sleep, I usually get interrupted in the middle of my thoughts or as i am sleeping by a sudden fear , guilt , sadness that seem to come out of no where . I panic so much that my heart starts to beat faster than ever , I feel like I am lost and I just want to cry . There are a lot of things that I think of during the day that upset me but usually I let them go until the night time when I am about to sleep and suddenly this just come to my mind and they freak me out and then I can't sleep for another 10 minutes or so . Usaulh ir would be about my concerns about the future or how will my life be and what I will do and that I wouldn't live for too long or what if I die , what if my family members died what if I never achieve my goals and end up depressed and all those stuff and thoughts make my heart beat fast and I don't know what to do . This has been going on for about 2 weeks now but every night it worsens kind of .
