Negative Thoughts

Hi all, I'm in my early days of Prozac treatment and the side effects are horrendous.... I am scared of going to sleep and have racing negative thoughts.... Managed 5 hrs sleep last night. So hard to stay positive at the minute .... I guess I'm being impatient. Everyone says that this is normal and I'm just trying to focus to get through each day by setting myself 3 positive targets.... Not easy but it is starting to get me through the day... The anxiety/ low moods come out of nowhere but the last couple of days they are not lasting as long.... I even managed to eat a little more yesterday.... It so reassuring to know I'm not the only one.
