pschotic depression

Hello everyone! I am a 22 year old female and I was wondering if anyone has had experience with pschotic depression. I go in to the doctor Tuesday but was looking for any input beforehand. I've done quit a bit of research on it but haven't found anything that has the same feelings I do.
Everyday I wake up, usually around 5 am when I don't have to be up until 9 am and try to go back to bed which takes a while to fall back asleep, I was up tired as hell with no energy every morning. I am constantly sad and on the verge of tears all day. I cry maybe two to three times a day sometimes for no reason what so ever just start crying. I have a hard time concentrating on things and have had conplaints that when i am asked someyhing i have an emotionless face and take a minute to answer, i an indecisive and can't make the easiest decisions. Everything that is said to me I take it in a negative way and it crushes me usually resulting in me crying again which is putting a real strain on my relationship. For example say I make my boyfriend a sandwich and he says "thank you for the sandwich but next time can you put a little less mustard" (we're still in the learning each other phase) I immediately take that as you messed my whole meal up, you can't do anything right, your stupid, etc all these feelings come rushing to my head and no matter what he says afterwards I can't stop those thoughts from filling my head. I constantly feel very guilty having a constant knot in my stomach from feeling so guilty, even if I haven't done anything wrong ill drag up something from the past to feel guilty about. I am extremely irritable and tired all of the time. I don't enjoy things that I used to love to do, I don't go out wih my friends or even to their house anymore, it's a chore for me to get out of my yoga pants let alone straighten my hair. I have also had a weight gain of about 50 pounds within the last year and a huge appetite! When I'm at work and my boyfriend is at home and e has a friend come over I'm constantly thinking that his friend is over there telling him bad things about me trying to get him to break up with me, or when he's at his brothers I think they're constantly talking negative things about me. Ill be sitting in the bedroom watching tv since that's all I seem to do lately and ill hear him and his dad talkig and automatically assume its something bad about me and I get sick to my stomach guilty again when they're not talking about me. I am also extremely paranoid, especially at night time. I always think someone is following me or trying to kill me, I won't walk from my house to car at night time for fear someone will get me. I also won't walk from the bedroom into the kitchen at night time even if my boyfriends home without a huge fear! I won't sit on a couch that doesn't have it's back to a wall for fear someone will come up behind me, I won't blow dry my hair when I'm home alone because if something does happen noone will be able to hear me call for ell because the blow driers on, I also won't wear red at night time because werewolves are attracted to red. I know how crazy all of this sounds and I know none of it is true but when I'm standing there trying to work up the courage to walk out the front door, I can't help but believe these thoughts. I try talking to my family about it but they all just brush it under the rug an tell me to just think positive and to stop being so negative all the time like I have a choice. If anyone has pschotic depression and can tell me if any of this makes sense with your symptoms I'd really appreciate it, thank you! Oh I also have the worse memory ever and can't remember past events or even if you tell me something ill have no recollection of it the next day or even within a couple hours ad then feel horrible for not being able to remember anything.
