hi celeste....i really sympathize with your situation. i have dealt on and off with fairly mild depression for the last several years. i am a nurse and am not a person who likes to take medication either but i have to say, the two times in my life i have needed it, it has been a big help. that being said, i did not feel safe and comfortable (no matter how much "they" say it's okay) with taking anti-depressants during pregnancy so i stopped when my husband and i were going to start trying for our first child, who is now almost 4. i was then off of them until about 6 months ago, when trying to keep up with being the mother of two (i now have another sweetheart who is 15 months old), working, and keeping up a household started to wear on me a little. the 1st trimester is such a trying time and the "sad" and tired that you feel when pregnant is hard to deal with when added on to existing feelings of "sad" and tired. this is so rambling, but i just want you to know you are definitely not the only one.
I should also say that i have been in counseling pretty regularly for the past 3 1/2 years and i LOVE it! my husband and i go together and i cannot tell you how much it has enriched our relationship and our family life. you not only learn more about yourself but you are learning more about your spouse.i am not sure about your husband's thoughts/ideas on this type of situation but it may actually be good for him to hear your discussion with your midwife on this topic. She will, of course, validate your feelings on this and it may be good for him to hear that you're not just being a "hormonal," "irrational," pregnant woman.
as for morning sickness, hopefully you're almost done but if you're not, i also highly recommend zofran. it is non-drowsy (compared to other anti-nausea meds) and is pretty harmless to your sweet baby you're caring. most mommies i know, myself included, have their nausea end a little after the beginning of the 2nd trimester even though they say that it's usually only in the 1st trimester.
well, i obviously need to go to sleep after working evening shift now because i have rambled on tooooo long. best wishes to you and just remember to take it easy on yourself and not judge yourself too much during this time even though others may try to. good luck! :)
